Pin Definitions and Functions TLE4699E (PG-SSOP-14 EP

)

Symbol

Function

RADJ

Reset Threshold Adjust

Connect an external voltage divider to adjust reset threshold;

Connect to GND for using internal threshold.

Reset Delay

Connect a ceramic capacitor from D (Pin 3) to GND for reset delay time adjustment;

Leave open, if the reset function is not needed.

GND

Ground

Connect to heat sink area.

5EN

Enable

High signal enables the regulator;

Low signal disables the regulator;

Connect to I if the enable function is not needed

7RO

Reset Output

Open collector output with an internal pull-up resistor to the output Q;

An additional external pull-up resistor to the output Q is optional;

Leave open if the reset function is not needed.

8SO

Sense Output

Open collector output with an internal pull-up resistor to the output Q;

An additional external pull-up resistor to the output Q is optional;

Leave open if the sense function is not needed.

5 V Regulator Output

Connect a capacitor between Q (Pin 11) and GND close to the IC pins, respecting the

values given for its capacitance CQ and ESR in the table Chapter 4.2 Functional Range.

Regulator Input and IC Supply

For compensating line influences, a capacitor to GND close to the IC pin is

recommended.

Sense Input

Connect the voltage rail to be monitored;

Connect to Q if the sense comparator is not needed.
