Pin Definitions and Functions

Pin

Symbol Function

1, 2, 19, 13 N.C.

Not connected

3

QRES

Reset output; open-collector output connected to the

output via a resistor of 30 kΩ.

4-7,

14-17

GND

Ground

9

DRES

Reset delay; connected to ground with a capacitor.

10

SRES

Reset threshold; for setting the switching threshold

connect with a voltage divider from output to ground. If this

input is connected to GND, reset is triggered at an output

voltage of 4.5 V.

11

W

Watchdog; positive edge triggered input for monitoring a

microcontroller.

12

VQ

5-V output voltage; block to ground with a 22−µF

capacitor.

18

VI

Input voltage; block to ground directly at the IC with a

ceramic capacitor.

20

INH

Inhibit; TTL-compatible, low-active input.
