Pin Definitions and Functions (TLE 4261 G)

Pin

Symbol Function

18

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.

20

INH

Inhibit; switches off the IC when low.

3

QRES 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

VQ

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

ESR is ≤ 3 Ω in the operating temperature range.
