Symbol Function

1

WO

Watchdog Output; the open collector output is connected to the

5 V output via an integrated resistor of 30 kΩ.

2

WADJ Watchdog Adjust; an external resistor to GND determines the

watchdog activating threshold.

Ground

6

D

Reset Delay; connect a capacitor to ground for delay time

adjustment.

7

RADJ Reset Switching Threshold Adjust; for setting the switching

threshold, connect a voltage divider from output to ground. If this

input is connected to ground, the reset is triggered at the internal

threshold.

8

WI

Watchdog Input; rising edge-triggered input for monitoring a

microcontroller.

9

Q

5 V Output Voltage; block to ground with min. 10 µF capacitor,

ESR ≤ 5 Ω.

13

I

Input Voltage; block to ground directly on the IC with ceramic

capacitor.

14

RO

Reset Output; the open collector output is connected to the 5 V

output via an integrated resistor of 30 kΩ.
