3 / 16 page TLE 4263 Semiconductor Group 3 1998-11-01 Pin Definitions and Functions Pin Symbol Function 1, 2, 19, 13 N.C. Not connected 3QRES Reset output; open-collector output connected to the output via a resistor of 30 k Ω. 4-7, 14-17 GND Ground 9 DRES Reset delay; connected to ground with a capacitor. 10 SRES Reset threshold; for setting the switching threshold connect with a voltage divider from output to ground. If this input is connected to GND, reset is triggered at an output voltage of 4.5 V. 11 W Watchdog; positive edge triggered input for monitoring a microcontroller. 12 V Q 5-V output voltage; block to ground with a 22 −µF capacitor. 18 V I Input voltage; block to ground directly at the IC with a ceramic capacitor. 20 INH Inhibit; TTL-compatible, low-active input. |
