A global FAULT pin is used to monitor the global fault condition among all the channels. When a fault condition occurs on any channel, the FAULT pin is pulled down to GND. A 3.3-V or 5-V external pullup is required to match the supply level of the house-keeping processor.

After the FAULT report, the processor can check and identify the channel in fault status by using the multiplexed current sensing pin. The CS pin also works as a fault report with an internal pullup voltage, V_{CS_FAULT}.
