Description

Positive Power Supply Input. Connect 0.1 mF capacitor to ground.

Reset Output. 30 kW internal Pull−up resistor connected to Vout. RO goes Low when Vout

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 Vout to select time.

Regulated Output Voltage. Connect 1 mF capacitor with ESR < 100 W to ground.
