Pin Definitions and Functions TLE42994G (PG-DSO-8)

Symbol

Function

Input

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

recommended

2SI

Sense Input

connect the voltage to be monitored;

connect to Q if the sense comparator is not needed

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

GND

Ground

6RO

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

7SO

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 “Functional Range” on Page 10

GND

RADJ
