Function
Watchdog Input
Positive edge triggered input, usable for microcontroller monitoring.
Connect to GND if the watchdog function is not needed.
5 V Regulator Output
Block to GND with a capacitor close to the IC pins, respecting capacitance and ESR
requirements given in the
Regulator Input and IC Supply
For compensating line influences, a capacitor to GND close to the IC pins is
recommended.
Reset Output
Open collector output with an internal pull-up resistor to the output Q.
An additional external pull-up resistor to the output Q is optional.
Leave open if the reset function is not needed.
