Description
Positive Power Supply Input. Connect 0.1 m F capacitor to ground.
Reset Output. 30 k W internal Pull ? up resistor connected to V out . RO goes Low when V out
drops by more than 7% (typ) from its nominal value (for NCV8772y devices with y = 1,2,3,...)
or more than 10% (typ) from its nominal value (for NCV8772y devices with y = A, B, C,...).
Not Connected
Power Supply Ground.
Enable Input. Low level disables the IC.
Reset Delay Time Select. Short to GND or connected to V out to select time.
Regulated Output Voltage. Connect 1 m F capacitor with ESR < 100 W to ground.
