Pin Description
PIN
NAME
FUNCTION
1IN
Voltage Input. IN is both the power-supply input and the overvoltage/undervoltage sense input. Bypass IN to
GND with a 1F ceramic capacitor as close as possible to the device to enable ±15kV (HBM) ESD protection
on IN.
2
GND
Ground
3
FLAG
Fault Indication Open-Drain Output. FLAG deasserts high during undervoltage and overvoltage lockout
conditions. FLAG asserts low during normal operation.
4
GATE
pFET Gate Drive Output. GATE is driven high during a fault condition to turn off the external pFET. When
VUVLO < VIN < VOVLO, GATE is driven low and the external pFET is turned on.
5, 6
N.C.
No Connection. Not internally connected. Leave N.C. unconnected.
