PIN FUNCTION DESCRIPTION
Pin No.

Type
Description
1
EN
INPUT
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.
2
GND
POWER
Ground
3
IN
POWER
Input Voltage Pin. This pin is connected to the VBUS. A 1 F low ESR ceramic capacitor, or larger,
must be connected between this pin and GND.
4, 5
OUT
OUTPUT
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 F capacitor must be connected to these pins.
The two OUT pins must be hardwired to common supply.
6
FLAG
OUTPUT
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.
