For example, Apple's iPod and iPhone chargers indicate the available current by voltages on the D− and D+ lines. Micro-A adapters allow for connection to standard-A plugs, as used on fixed or standard devices. However, some of this directed topology is lost with the advent of multi-purpose USB connections (such as USB On-The-Go in smartphones, and USB-powered Wi-Fi routers), which require A-to-A, B-to-B, and sometimes Y/splitter cables. The connectors were different so that users could not connect one computer receptacle to another. [65] Power Delivery protocols have been updated to facilitate USB-C features such as cable ID function, Alternate Mode negotiation, increased VBUS currents, and VCONN-powered accessories. An OTG cable has a micro-A plug on one end, and a micro … dewalt usb charger iphone charger usb c dewalt phone charger 25 ft usb cables mini-b usb … Where devices (for example, high-speed disk drives) require more power than a high-power device can draw,[46] they function erratically, if at all, from bus power of a single port. First of all, it’s important to understand what exactly a USB connector type is. [13] Mini-B connectors are still supported, but are not On-The-Go-compliant;[14] the Mini-B USB connector was standard for transferring data to and from the early smartphones and PDAs. However, such devices may come with a Y-shaped cable that has two USB plugs (one for power and data, the other for only power), so as to draw power as two devices. Up to 5 unit loads; with non-SuperSpeed devices, one unit load is 100 mA. Both Mini-A and Mini-B plugs are approximately 3 by 7 mm (0.12 by 0.28 in). Alternate Mode dedicates some of the physical wires in the USB-C cable for direct device-to-host transmission of alternate data protocols. Recognized by the USB-IF, this connector can also be found on newer mobile devices such as cellphones, GPS units, PDAs and digital cameras. The OTG device with the A-plug inserted is called the A-device and is responsible for powering the USB interface when required, and by default assumes the role of host. There are five speeds for USB data transfer: Low Speed, Full Speed, High Speed (from version 2.0 of the specification), SuperSpeed (from version 3.0), and SuperSpeed+ (from version 3.1). It draws 1 unit load for the hub controller and 1 unit load for each of at most 4 ports. The EU's common EPS specification (EN 62684:2010) references the USB Battery Charging Specification and is similar to the GSMA/OMTP and Chinese charging solutions. Otherwise, connecting a device could cause problems with the host's internal power. (In the past, before the development of Micro-USB, On-The-Go devices used Mini-AB receptacles). [34], Some manufacturers now offer USB magnetic port adapters; as of 2018 all product are proprietary incompatible designs. The primary reason for this limit is the maximum allowed round-trip delay of about 1.5 μs. ", "Deprecation of the Mini-A and Mini-AB Connectors", "ID Pin Resistance on Mini B-plugs and Micro B-plugs Increased to 1 Mohm", "Mobile phones to adopt new, smaller USB connector", "Micro-USB pinout and list of compatible smartphones and other devices", "Universal Serial Bus Micro-USB Cables and Connectors Specification to the USB 2.0 Specification, Revision 1.01", "OMTP Local Connectivity: Data Connectivity", "Universal phone charger standard approved—One-size-fits-all solution will dramatically cut waste and GHG emissions", "Commission welcomes new EU standards for common mobile phone charger", "Nice Micro-USB adapter Apple, now sell it everywhere", "Apple's Lightning to Micro-USB adapter now available in US, not just Europe anymore", "USB-C vs. USB 3.1: What's the difference?

This connector … [49][50], Per the base specification, any device attached to a standard downstream port (SDP) must initially be a low-power device, with high-power mode contingent on later USB configuration by the host. In most cases, these items contain no digital circuitry, and thus are not standard-compliant USB devices. The modes have differing hardware and cabling requirements. In a charge-only cable, the data wires are shorted at the device end, otherwise the device may reject the charger as unsuitable. The USB standard included power supply to peripheral devices; modern versions of the standard extend the power delivery limits for battery charging and devices requiring up to 100 watts. [52], Before the Battery Charging Specification was defined, there was no standardized way for the portable device to inquire how much current was available. This change was made so that the connector on the less expensive cable would bear the most wear. Revision 3.0 also adds extended configuration messages, fast role swap, and deprecates the BFSK protocol. [citation needed] The four high-speed lanes, two sideband pins, and‍—‌for dock, detachable device and permanent cable applications only‍—‌two USB 2.0 pins and one configuration pin can be used for Alternate Mode transmission. The USB specification also defines limits to the size of a connecting device in the area around its plug, so that adjacent ports are not blocked. When a device detects it is plugged into a charger with a compatible faster-charging standard, the device pulls more current or the device tells the charger to increase the voltage or both to increase power (the details vary between standards).[100]. "[48], USB Battery Charging defines a charging port, which may be a charging downstream port (CDP), with data, or a dedicated charging port (DCP) without data. Micro USB Micro USBs are another miniaturized version of USB interfaces. Adapters and cables with a USB-C receptacle are not allowed.[31]. Normally, when a computer is powered off the USB ports are powered down. It replaces other connection types as of USB 3.2 onwards. Micro Center is passionate about providing product expertise and exceptional customer service at each of our locations. An OTG device with no plug inserted defaults to acting as a B-device. Such devices can use an external power supply, which is allowed by the standard, or use a dual-input USB cable, one input of which is for power and data transfer, the other solely for power, which makes the device a non-standard USB device. This creates the infamous one-sided USB connection that only works when the cable is insert… This may cause problems with some computers, such as drawing too much current and damaging circuitry. USB de… [39] The USB 2.0 specification requires that cable delay be less than 5.2 ns/m (1.6 ns/ft), (192000 km/s) - which is close to the maximum achievable transmission speed for standard copper wire). 45, International Electrotechnical Commission (IEC), "USB 2.0 Specification Engineering Change Notice (ECN) #1: Mini-B connector", "Universal Serial Bus Cables and Connectors Class Document Revision 2.0", "USB Type-C Connector Specifications Finalized", "Why was Mini-USB deprecated in favor of Micro-USB? Get it as soon as Tue, Dec 1. Up to 6 unit loads; with SuperSpeed devices, one unit load is 150 mA. [57][67][68], As of April 2016[update], there are silicon controllers available from several sources such as TI and Cypress. In some sources D+ and D− are erroneously swapped. Only downstream facing ports provide power; this topology was chosen to easily prevent electrical overloads and damaged equipment. [97][98] In January 2011, the International Electrotechnical Commission (IEC) released its version of the (EU's) common EPS standard as IEC 62684:2011. This is common for external hard and optical disc drives, and generally for devices with motors or lamps. With an adapter, this is compatible with all USB except for USB 1. [69][70] Power supplies bundled with USB-C based laptops support USB PD. On the device side, a modified Micro-B plug (Micro-B SuperSpeed) is used to cater for the five additional pins required to achieve the USB 3.0 features (USB-C plug can also be used). High-retention connector, mostly used on industrial hardware. [citation needed], The D± signals used by low, full, and high speed are carried over a twisted pair (typically unshielded) to reduce noise and crosstalk. You’re seeing this ad based on the product’s relevance to your search query. PoweredUSB is a proprietary extension that adds four additional pins supplying up to 6 A at 5 V, 12 V, or 24 V. It is commonly used in point of sale systems to power peripherals such as barcode readers, credit card terminals, and printers. The USB Power Delivery specification revision 2.0 (USB PD Rev. It can be found in many devices like mobile phones, cameras. [89][90], The GSM Association (GSMA) followed suit on 17 February 2009,[91][92][93][94] and on 22 April 2009, this was further endorsed by the CTIA – The Wireless Association,[95] with the International Telecommunication Union (ITU) announcing on 22 October 2009 that it had also embraced the Universal Charging Solution as its "energy-efficient one-charger-fits-all new mobile phone solution," and added: "Based on the Micro-USB interface, UCS chargers will also include a 4-star or higher efficiency rating—up to three times more energy-efficient than an unrated charger. $6.99$6.99. Also, it is the same for micro USB type-a and micro USB type-b. To allow for voltage drops, the voltage at the hub port is specified in the range 4.40–5.25 V by USB 2.0, and 4.45–5.25 V[41][not specific enough to verify] by USB 3.0. Bus power is also provided to the accessory port from the charging port transparently. A bus-powered hub is a high-power device providing low-power ports. The ID pin of the OTG port is not connected within plug as usual, but to the ACA itself, where signals outside the OTG floating and ground states are used for ACA detection and state signaling. Toshiba calls it USB Sleep-and-Charge. Some devices that use Type-A connectors are mouse, keyboard, or network adapter, and even thumb drives (USB … When a device doesn't recognize the faster-charging standard, generally the device and the charger fall back to the USB battery-charging standard of 5 V at 1.5 A (7.5 W). Micro USB type A: This type is one of the most common types, It allowed the manufacturers to produce slimmer devices. Micro-USB B offers a connection physically smaller in size to a USB … [83] On Acer Inc. and Packard Bell laptops, sleep-and-charge USB ports are marked with a non-standard symbol (the letters USB over a drawing of a battery); the feature is called Power-off USB. USB On-The-Go (OTG) introduces the concept of a device performing both master and slave roles. 1), an extension that specifies using certified PD aware USB cables with standard USB Type-A and Type-B connectors to deliver increased power (more than 7.5 W) to devices with greater power demands. Micro-USB connectors, which were announced by the USB-IF on 4 January 2007,[15][16] have a similar width to Mini-USB, but approximately half the thickness, enabling their integration into thinner portable devices. [76], Prior to Power Delivery, mobile phone vendors used custom protocols to exceed the 7.5 W cap on USB-BCS. Consumers got fed up with … Full functionality of proprietary ports and cables with USB standard ports is not assured; for example, some devices only use the USB connection for battery charging and do not implement any data transfer functions. [47] Such a cable is non-standard, with the USB compliance specification stating that "use of a 'Y' cable (a cable with two A-plugs) is prohibited on any USB peripheral", meaning that "if a USB peripheral requires more power than allowed by the USB specification to which it is designed, then it must be self-powered. The shell is typically grounded, to dissipate static electricity and to shield the wires within the connector. Charging docks supply power and do not include a host device or data pins, allowing any capable USB device to charge or operate from a standard USB cable. SanDisk - Ultra 128GB USB 3.1, USB … Micro-USB A offers a connection physically smaller in size to a USB Mini-b, while still supporting the high speed transfer rate of 480 Mbps and On-The-Go features. Optionally, the hub controller may draw power for its operation as a low-power device, but all high-power ports draw from the hub's self-power. [99], A variety of (non-USB) standards support charging devices faster than the USB battery-charging standard (USB-#BCS). USB Type-A. The mini and micro formats also provide for USB On-The-Go with a hermaphroditic AB receptacle, which accepts either an A or a B plug. An OTG product must have a single micro-AB receptacle and no other USB receptacles. Each format has a plug and receptacle defined for each of the A and B ends. [5] To accomplish this, a locking device was added and the leaf-spring was moved from the jack to the plug, so that the most-stressed part is on the cable side of the connection. USB provides for these devices as being self-powered. If an application on the B-device requires the role of host, then the Host Negotiation Protocol (HNP) is used to temporarily transfer the host role to the B-device. [86][87] This was the first standard to use the convention of shorting D+ and D− in the charger. Micro USB is a miniaturized version of the Universal Serial Bus (USB) interface developed for connecting compact and mobile devices such as smartphones, Mp3 players, GPS devices, photo … The small size of Micro USBs allowed manufacturers to produce slimmer devices. Several changes are made and limits are increased including allowing 1.5 A on charging downstream ports for unconfigured devices, allowing High Speed communication while having a current up to 1.5 A, and allowing a maximum current of 5 A. Charging cables provide power connections, but not data. This ID pin is connected to GND in Type-A plugs, and left unconnected in Type-B plugs. Up to 6 unit loads; with multi-lane devices, one unit load is 250 mA. The modes have differing hardware and cabling requirements. The female connector mounted on the host or device is called the receptacle, and the male connector attached to the cable is called the plug. The very small USB port found on many non-Apple cellphones, tablets and other portable devices is a Micro USB socket. The three sizes of USB connectors are the default or standard format intended for desktop or portable equipment, the mini intended for mobile equipment, and the thinner micro size, for low-profile mobile equipment such as mobile phones and tablets. That’s it for the so-called “standard” ports, but there are … This feature has also been implemented on some laptop docking stations allowing device charging even when no laptop is present. Micro USB is the Universal Serial Bus’ (USB) mini version. Devices can request higher currents and supply voltages from compliant hosts – up to 2 A at 5 V (for a power consumption of up to 10 W), and optionally up to 3 A or 5 A at either 12 V (36 W or 60 W) or 20 V (60 W or 100 W). 57 [53] When D+ = 2.8 V and D− = 2.0 V, the device may pull up to 2 A of current.[54]. SuperSpeed uses separate transmit and receive differential pairs, which additionally require shielding (typically, shielded twisted pair but twinax is also mentioned by the specification). USB ports and connectors are often color-coded to distinguish their different functions and USB versions. FREE Shipping on … Australian and New Zealand power socket with USB charger socket. The Micro USB was developed to standardize and streamline phone charging devices. [33] Some manufacturers such as Apple provide proprietary cables that permit their devices to physically connect to a USB standard port. The versatile Mini microphone is on sale. The UUSBHAUB3 3-foot USB A to Micro USB cable features one USB ‘A’ male connector, and one ‘Micro-B’ male connector, providing a high quality connection to USB 2.0 mobile devices (such as BlackBerry® or Android-based cellular phones, digital cameras, PDA’s, Tablet PC devices and GPS systems) that use a Micro USB connector to a USB … Many people might be reading this ask themselves, “Are there really more types of USB connectors?” The answer, of course, is yes. [citation needed] On Dell, HP and Toshiba laptops, the port is marked with the standard USB symbol with an added lightning bolt or battery icon on the right side. Accessory charging adapters (ACA) are devices that provide portable charging power to an On-The-Go connection between host and peripheral. > 3 A (60 W) operation requires an electronically marked cable rated at 5 A. If you are a seller and want to participate in this program click here to learn more. When D+ = D− = 2.0 V, the device may pull up to 900 mA. ACAs have three ports: the OTG port for the portable device, which is required to have a Micro-A plug on a captive cable; the accessory port, which is required to have a Micro-AB or type-A receptacle; and the charging port, which is required to have a Micro-B receptacle, or type-A plug or charger on a captive cable. To enable Type-AB receptacles to distinguish which end of a cable is plugged in, plugs have an "ID" pin in addition to the four contacts in standard-size USB connectors. The pinout diagram for the micro USB type-B very similar to USB type-A except for the last two pins 4 and 5. Prior to the USB Battery Charging Specification, the USB specification required that devices connect in a low-power mode (100 mA maximum) and communicate their current requirements to the host, which then permits the device to switch into high-power mode. The Micro-A connector is 6.85 by 1.8 mm (0.270 by 0.071 in) with a maximum overmold boot size of 11.7 by 8.5 mm (0.46 by 0.33 in), while the Micro-B connector is 6.85 by 1.8 mm (0.270 by 0.071 in) with a maximum overmold size of 10.6 by 8.5 mm (0.42 by 0.33 in). On-The-Go allows USB between peers without discarding the directed topology by choosing the host at connection time; it also allows one receptacle to perform double duty in space-constrained applications. [58] In all cases, both host-to-device and device-to-host configurations are supported. A self-powered hub is a device that provides high-power ports. As of USB Power Delivery specification revision 2.0, version 1.2, the six fixed power profiles for power sources have been deprecated. A variety of USB cables, including micro-USB, mini-USB, and standard USB. Revision 1.2 of the specification was released in 2010. 2.0) has been released as part of the USB 3.1 suite. The charging port does not pass data, but does use the D± signals for charging port detection. There are cables with A plugs on both ends, which may be valid if the cable includes, for example, a USB host-to-host transfer device with 2 ports.[3]. [85], As of 14 June 2007[update], all new mobile phones applying for a license in China are required to use a USB port as a power port for battery charging. Some USB ports and external hubs can, in practice, supply more power to USB devices than required by the specification but a standard-compliant device may not depend on this. A dedicated charging port places a resistance not exceeding 200 Ω across the D+ and D− terminals. The shell on the plug makes contact with the receptacle before any of the internal pins. USB devices are also required to automatically enter ultra low-power suspend mode when the USB host is suspended. The pin no.1 is +5V acts as a source … Devices' configuration and low-power functions must operate down to 4.40 V at the hub port by USB 2.0 and that devices' configuration, low-power, and high-power functions must operate down to 4.00 V at the device port by USB 3.0.
