Usb Otg Id Resistor

- July 29, 2019

Before usb otg was popular the 5th pin was an auxiliary pin to allow the usb port on portable devices to be used for other purposes via passive componentscircuits. If you want swichon otg host function charging of host device together this provide by usb standard resistance 124kohms even is allowed range 119 132 kohms between mentioned pins 4 and 5.

According to usb spec if id pin is gnd it is device a if id pin is open it is device b.

Usb otg id resistor. You need a pull up resistor on the id pin. Resistor rd pull down between cc and gnd id pin. The mini b plug leaves the fifth pin unconnected.

Non powered hub or powered hub or regular female usb connector for mouse keyboard gamepads etc 100k ohm resistor for enable otg mode and cgarging tested on sony xperia s working fine on other devicecs you may need to use other resistor with different value. Otg receptacles and plugs contain a fifth pin added to the standard four usb pins vbus gnd d and d. The usb on the go logo usb on the go usb otg or just otg is a specification first used in late 2001 that allows usb devices such as tablets or smartphones to act as a host allowing other usb devices such as usb flash drives digital cameras mice or keyboards to be attached to them.

Usb cables with micro usb and full size usb ends soldering iron and solder wire cutters wire strippers dremel or something else to cut and expose a usb cables circuit board resistor to make a sony compatible usb otgcharging y cable use a 100k ohm resistor. The otg spec resolves this question in a very simple manner. Usb c receptacle to microb plug.

Miniab pin 4 id is shorted to pin 5 ground to indicate mini ab is in host mode. Usb c plug to type a receptacle. Usb type c plug to usb 31 type a plug.

Usb c plug to microb plug. Sometimes this could be a composite tv out. Device a source vbus.

However how this happens if id pin is connected both devices. Usb id is connected to ground host 0. Usb c plug to usb 20 type a plug.

Not allowed per the spec. With the id pin at ground gnd the otg product functions as a usb host and provides v bus to the attached usb peripheral. Usb id is pulled high device 1.

Very old usb if mechanical presentation. To build your own youll need a few tools and supplies. Is a fifth pin in the connector not a fifth wire in the cable.

By the usb standard is otg host function switchedon at host device phone tablet etc by short connection 0 ohm between pins 4 id and 5 gnd on microusb male plug. Table 1 shows the pin out for both receptacle and plug. After hnp vbus will be switched to device b.

A resistor array in the cable would indicate the function of the cable to circuitry in the device. Otherwise the otg device functions as a usb peripheral. Implementing usb 20 otg determines its role as either a host or a peripheral by the state of the id pin.
