Pin Definitions and Functions TLE42994GM (PG-DSO-14)

Symbol

Function

RADJ

Reset Threshold Adjust

connect an external voltage divider to adjust reset threshold;

connect to GND for using internal threshold

Reset Delay Timing

connect a ceramic capacitor to GND for adjusting the reset delay time;

leave open if the reset function is not needed

3, 4, 5

GND

Ground

connect all pins to PCB and heatsink area

6EN

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; internally linked to the output via a 20k

Ω pull-up resistor;

leave open if the reset function is not needed

8SO

Sense Output

open collector output; internally linked to the output via a 20k

Ω pull-up resistor;

leave open if the sense comparator is not needed

Output

block to GND with a capacitor close to the IC terminals, respecting the values given

for its capacitance CQ and ESR in the table “Functional Range” on Page 10

10, 11, 12

GND

Ground

connect all pins to PCB and heatsink area

Input

for compensating line influences, a capacitor to GND close to the IC terminals is

recommended

Sense Input

connect the voltage to be monitored;

connect to Q if the sense comparator is not needed
