Function

Reset Threshold Adjust; if not used to connect to GND.

Reset Delay; To Set Time Delay, Connect to GND with Capacitor

Ground

NC

No connection to these pins from the IC.

RO

Reset Output; The Open−Collector Output has a 20 kW Pullup Resistor to

Q. Leave Open if Not Used.

SO

Sense Output; This Open−Collector Output is Internally Pulled Up by

20 kW pullup resistor to Q. If not used, keep open.

Q

5 V Output; Connect to GND with a 10 mF Capacitor, ESR < 10 W.

I

Input; Connect to GND Directly at the IC with a Ceramic Capacitor.

SI

Sense Input; If not used, Connect to Q.
