Fault Indication Pin.
This pin allows an external system to detect a fault on IN pin.
The FLAG pin goes low when input voltage exceeds OVLO threshold or drop below UVLO threshold.
Since the FLAG pin is open drain functionality, an external pull up resistor to V
Enable Pin.
The device enters in shutdown mode when this pin is tied to a high level. In this case the output is
disconnected from the input.
To allow normal functionality, the EN pin shall be connected to GND to a pull down or to a I/O pin.
This pin does not have an impact on the fault detection.
Input Voltage Pin.
This pin is connected to the power supply.
The device system core is supplied by this input.
A 1 mF low ESR ceramic capacitor, or larger, must be connected between this pin and GND.
The three IN pins must be hardwired to common supply.
Ground
Output Voltage Pin.
This pin follows IN pin when “no fault” is detected.
The output is disconnected from the V
threshold or above OVLO threshold.
The two OUT pins must be hardwired to common supply.

Can be shorted to GND.
The PAD2 is electrically connected to the internal NMOS drain and connected to Pins 4 and 5.
