8.3.2 Short-to-Battery and Short-to-Ground Protection on VBUS_CON

The VBUS_CON pin is protected against shorts to battery and shorts to ground.

Once a voltage on VBUS_CON is detected as too low (below the VSHRT threshold) after the device is enabled, the device enters short-circuit protection mode and assert FLT. It sources the ISHRT current until it detects the voltage rising above the VSHRT threshold, where it resumes standard operating mode and deassert FLT.

Once a voltage above the VOVP threshold is detected by the device, it shuts off all FETs and asserts a fault on the FLT pin. Once the excessive voltage is removed, the device automatically re-enables and FLT deasserts (see the Timing Requirements table for more details).
