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
