Symbol

Function

18

V

I

Input voltage; block a capacitor directly to ground on the IC. The

capacitor rating will depend on the vehicle electrical system.

Oscillation of the input voltage can be damped by a resistor of

approx. 1

Ω in series with the input capacitor.

20

INH

Inhibit; switches off the IC when low.

3QRES

Reset output; open-collector output controlled by the reset

delay.

4 - 7

14 - 17

GND

Ground; internally connected with pins 14 to 17.

9

DRES

Reset delay; wired to ground using a capacitor.

11

Watch

Watchdog; monitors the microprocessor when active.

12

V

Q

5-V output voltage; block to ground using a capacitor of

≥ 22 µF.

ESR is

≤ 3 Ω in the operating temperature range.
