Pin Definitions and Functions (TLE 4261; S)

Pin

Symbol

Function

1

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.

2INH

Inhibit; switches off the IC when low.

3QRES

Reset output; open-collector output controlled by the rese delay.

4GND

Ground

5DRES

Reset delay; wired to ground using a capacitor.

6Watch

Watchdog; monitors the microprocessor when active.

7

V

Q

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

≥ 22 µF.

ESR is

≤ 3 Ω in the operating temperature range.
