Hi everybody,
I need some help and I´d really appreciate that.
I want to design an USB OTG device, which could be either host or device.
The used USB transceiver has an enable pin which could used for enabling an external VBus power supply (blue line). So, if the device is "host", the VBus power supply should be enabled by the USB transceiver and if the device is "device", the USB transceiver should disable the power supply.
Can I use the TPS2500 according to the block diagram above ?
Or do I have to consider the reverse current from VBus to the TPS2500 ?
Thanks to anyone who can help me !
Andy
