3.4 Pin Definitions and Functions TLE42994GM (PG-DSO-14)
Pin Symbol Function
1
RADJ
Reset Threshold Adjust
connect an external voltage divider to adjust reset threshold;
connect to GND for using internal threshold
2D 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 20kΩ 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 20kΩ pull-up resistor;
leave open if the sense comparator is not needed
9Q Output
block to GND with a capacitor close to the IC terminals, respecting the values given
for its capacitance C
Q
and ESR in the table “Functional Range” on Page 10
10, 11, 12
GND
Ground
connect all pins to PCB and heatsink area
13 I
Input
for compensating line influences, a capacitor to GND close to the IC terminals is
recommended
14 SI Sense Input
connect the voltage to be monitored;
connect to Q if the sense comparator is not needed
