Description
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 or to a I/O pin. This pin does not have an impact on the fault detection.
Ground
Input Voltage Pin. This pin is connected to the VBUS. A 1 m F low ESR ceramic capacitor, or larger,
must be connected between this pin and GND.
Output Voltage Pin. The output is disconnected from the VBUS power supply when the input voltage is
above OVLO threshold or below UVLO threshold. A 1 m F capacitor must be connected to these pins.
The two OUT pins must be hardwired to common supply.
Fault Indication Pin. This pin allows an external system to detect a fault on VBUS pin. The FLAG pin
goes low when input voltage exceeds OVLO threshold. Since the FLAG pin is open drain functionality,
an external pull up resistor to V CC must be added.
