OC pin on TPS2051B

Other Parts Discussed in Thread: TPS2051B

Hi,

Would like to confirm the purpose of OCn pins on TPS2051B:

  1. According to USB 2.0 Spec there is a requirement for host and hub to detect overcurrent condition. Is this what the OCn pin is for?
  2. If the host processor uses 1.8V I/O, should we tie OCn to 1.8V instead of 3.3V?
