Pin Definitions and Functions (TLE 4261; S)

Pin

Symbol Function

1

VI

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.

2

INH

Inhibit; switches off the IC when low.

3

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

4

GND Ground

5

DRES Reset delay; wired to ground using a capacitor.

6

Watch Watchdog; monitors the microprocessor when active.

7

VQ

5-V output voltage; block to ground using a capacitor of ≥ 22 µF.

ESR is ≤ 3 Ω in the operating temperature range.
