An OTG product must have a single micro-AB receptacle and no other USB receptacles. Revision 1.2 of the specification was released in 2010. The 3.0 receptacles are backward-compatible with the corresponding pre-3.0 plugs. If USB host commands are unanswered by the USB device within the allowed time, the host considers the command lost. High-retention connector, mostly used on industrial hardware. USB cables have plugs, and the corresponding receptacles are on the computers or electronic devices. The limit to device power draw is stated in terms of a unit load which is 100 mA, or 150 mA for SuperSpeed devices. Dedicated charging ports can be found on USB power adapters to run attached devices and battery packs. [29][30] Type-A and Type-B adaptors and cables are required for older devices to plug into USB-C hosts. In this way, cables with smaller 5 pin USB 2.0 Micro-B plugs can be plugged into devices with 10 contact USB 3.0 Micro-B receptacles and achieve backward compatibility. Micro USB to USB A Adapter, 2 Pack USB A (Male) to Micro USB (Female) Convertor Adapter Compatible with Android Phone, Tablets and More. 2.0) has been released as part of the USB 3.1 suite. The USB standard specifies tolerances for compliant USB connectors to minimize physical incompatibilities in connectors from different vendors. [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. Since these currents are larger than in the original standard, the extra voltage drop in the cable reduces noise margins, causing problems with High Speed signaling. USB cables exist with various combinations of plugs on each end of the cable, as displayed below in the USB cables matrix. The standard connectors were designed to be more robust than many past connectors. This is common for external hard and optical disc drives, and generally for devices with motors or lamps. [49], The charging device identifies a charging port by non-data signaling on the D+ and D− terminals. Model# 34709 $ 7 99. USB-A is a traditional USB host port design and one of the easiest to recognize on devices. The very small USB port found on many non-Apple cellphones, tablets and other portable devices is a Micro USB socket. This feature has also been implemented on some laptop docking stations allowing device charging even when no laptop is present. [27] The USB-C plug connects to both hosts and devices, replacing various Type-A and Type-B connectors and cables with a standard meant to be future-proof. 98 - $19.96 $ 19 … 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. PD-aware devices implement a flexible power management scheme by interfacing with the power source through a bidirectional data channel and requesting a certain level of electrical power, variable up to 5 A and 20 V depending on supported profile. 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. 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. Mini and micro connectors have their GND connections moved from pin #4 to pin #5, while their pin #4 serves as an ID pin for the On-The-Go host/client identification.[7]. 57 For example, Apple's iPod and iPhone chargers indicate the available current by voltages on the D− and D+ lines. The USB specification requires that the cable plug and receptacle be marked so the user can recognize the proper orientation. [24][25] according to the CEN, CENELEC, and ETSI. 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. It draws 1 unit load for the hub controller and 1 unit load for each of at most 4 ports. Charging cables provide power connections, but not data. Communication connector using the USB protocol, USB 3.x connectors and backward compatibility. The Micro-USB interface is commonly found on chargers for mobile phones.

Some non-standard USB devices use the 5 V power supply without participating in a proper USB network, which negotiates power draw with the host interface. Accessory charging adapters (ACA) are devices that provide portable charging power to an On-The-Go connection between host and peripheral. [1] The official USB specification documents also periodically define the term male to represent the plug, and female to represent the receptacle.[2]. USB On-The-Go (OTG) introduces the concept of a device performing both master and slave roles. USB supplies power at 5 V ± 5% to power USB downstream devices. A high-powered device must be configured, after which it may draw up to 5 unit loads (500 mA) or 6 unit loads (900 mA) for SuperSpeed devices, as specified in its configuration. [59], The intent is to permit uniformly charging laptops, tablets, USB-powered disks and similarly higher-power consumer electronics, as a natural extension of existing European and Chinese mobile telephone charging standards. In Europe, micro-USB became the defined common external power supply (EPS) for use with smartphones sold in the EU,[21] and 14 of the world's largest mobile phone manufacturers signed the EU's common EPS Memorandum of Understanding (MoU). These are usually called USB decorations. In common practice, the A end is usually the standard format, and the B side varies over standard, mini, and micro.

[49], In July 2012, the USB Promoters Group announced the finalization of the USB Power Delivery (PD) specification (USB PD rev. (2) 8-pin Mini-B plug (this strongly resembles the 8-pin Micro-B plug which often has only 5 pin positions occupied), The type-A plug. This plug has an elongated rectangular cross-section, inserts into a type-A receptacle on a, The type-B plug: This plug has a near square cross-section with the top exterior corners beveled. [citation needed] Examples include USB-powered keyboard lights, fans, mug coolers and heaters, battery chargers, miniature vacuum cleaners, and even miniature lava lamps. 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). Some devices that use Type-A connectors are mouse, keyboard, or network adapter, and even thumb drives (USB … 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 … Quickview. [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. The modes have differing hardware and cabling requirements. Charging ports on a host with both kinds will be labelled. 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. The connection can be easily identified by its … USB devices have some choice of implemented modes, and USB version is not a reliable statement of implemented modes. These colors are not part of the USB specification and can vary between manufacturers; for example, USB 3.0 specification mandates appropriate color-coding while it only recommends blue inserts for standard-A USB 3.0 connectors and plugs.[10]. 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). The first Power Delivery specification defined six fixed power profiles for the power sources. Recognized by the USB-IF, this connector can also be found on newer mobile devices such as cellphones, GPS units, PDAs and digital cameras. USB connector types multiplied as the specification progressed. Revision 3.0 also adds extended configuration messages, fast role swap, and deprecates the BFSK protocol. Micro USB is the Universal Serial Bus’ (USB) mini version. SuperSpeed uses separate transmit and receive differential pairs, which additionally require shielding (typically, shielded twisted pair but twinax is also mentioned by the specification). The shell on the plug makes contact with the receptacle before any of the internal pins. The charging port must not apply current limiting below 0.5 A, and must not shut down below 1.5 A or before the voltage drops to 2 V.[49]. The micro USB technology was developed … [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. Some devices, when plugged into charging ports, draw even more power (10 watts at 2.1 amperes) than the Battery Charging Specification allows — The iPad is one such device;[102] it negotiates the current pull with data pin voltages.
