RESET
RESET signal output pin. The output remains
low while V
DET
is below the reset voltage
threshold, and for an extnerl set time delay
Cd pin after V
DET
rises above reset
threshold.

ON/OFF
Output voltage on/off control pin. Connect to
V

if not used.
ON/OFF = LOW: Voltage output (Pin 5) OFF
ON/OFF = HIGH: Voltage output (Pin 5) ON

Cd
Reset delay time capacitor pin.
RESET pin output delay time can be set by
capacitance connected to the Cd pin.
