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.
