I
Regulator Input and IC Supply
For compensating line influences, a capacitor to GND close to the IC pins is
recommended.

RO
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.
4
WO
Watchdog 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 watchdog function is not needed.
5
WADJ Watchdog Activating Threshold Adjust
An external resistor to GND determines the watchdog activating threshold.
Connect directly to GND for disabling the watchdog.
Connect directly to GND if the watchdog function is not needed.
Connect to output Q via 270 kΩ resistor for permanently activating the watchdog.
6
GND
IC Ground
Interconnect with the exposed pad and heatsink area on PCB.
