8.4.8 Faults

The TPS6602x includes a fault pin, FLT. The FLT pin is an open-drain output and requires an external pull-up resistor. If the FLT pin is not required, it may be tied to GND or left floating. The FLT pin will be asserted low only under certain conditions and not all fault conditions will assert the FLT pin, see Table 3. If the FLT pin is asserted, it will remain asserted for a minimum of tHOLD_FLT regardless if the fault condition is removed. After tHOLD_FLT, if all fault conditions have surpassed, the FLT pin is released.
