Pin Definitions and Functions

Pin No. Symbol Function

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

capacitor rating will depend on the vihicle electric system.

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

approx. 1

Ω in series with the input capacitor.

2INH

Inhibit; switches off the IC when low.

3QRES

Reset output; open collector output controlled by the reset delay.

4GND

Ground

DRES

Reset delay; wired to ground using a capacitor.

6Watch

Watchdog; monitors the microprocessor when active.

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

≥ 22-µF. ESR is

≤ 3 Ω in the operating temperature range.
