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.
