Pin Configuration
Pin Symbol Function
8
D
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.
9
n.c.
Not Connected
Internally not connected; Connection to PCB GND recommended.
10
WI
Watchdog Input
Positive edge triggered input, usable for microcontroller monitoring.
Connect to GND if the watchdog function is not needed.
11
n.c.
Not Connected
Internally not connected; Connection to PCB GND recommended
12
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.
13
n.c.
Not Connected
Internally not connected; Connection to PCB GND recommended.
14
Q
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.
PAD
Heat sink
connect to PCB heat sink area and GND
