The FLT pin is open drain and can report a fault signal to the DSP/MCU when overcurrent and short circuit faults are detected through the OC pin. The FLT pin is pulled down to GND, and is held in a low state unless a reset signal is received from RST/EN. The device has a fault mute time, tFLTMUTE, within which the device ignores any reset signal.
RST/EN is pulled down internally. The device is disabled by default if the RST/EN pin is floating. The pin has two purposes:
