Function
Reset Delay and Watchdog Timing
Connect a ceramic capacitor D (pin 6) to GND for reset delay and watchdog timing
adjustment.
Leave only open if both, the reset and the watchdog function are not needed.
Reset Switching Threshold Adjust
For reset threshold adjustment connect to a voltage divider from output Q to GND.
For triggering the reset at the internally determined threshold, connect this pin directly to
GND.
Connect directly to GND if the reset function is not needed.
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 Chapter 4.2.
Internally not connected
Connection to GND on PCB recommended.
Connect to heat sink area on PCB. Interconnect with GND.
