IN
Voltage Input. IN is both the power-supply input and the overvoltage/undervoltage sense input. Bypass IN to
GND with a 1µF ceramic capacitor as close as possible to the device to enable ±15kV (HBM) ESD protection
on IN.

Fault Indication Open-Drain Output. FLAG deasserts high during undervoltage and overvoltage lockout
conditions. FLAG asserts low during normal operation.
pFET Gate Drive Output. GATE is driven high during a fault condition to turn off the external pFET. When
