Function

Reset Threshold Adjust

connect an external voltage divider to adjust reset threshold;

connect to GND for using internal threshold

not connected

Reset Delay Timing

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

leave open if the reset function is not needed

Ground

connect all pins to PCB and heatsink area

Reset Output

open collector output; external pull-up resistor required, respecting values given in

Item 5.6.4;

leave open if the reset function is not needed

Sense Output

open collector output; external pull-up resistor required, respecting values given in

Item 5.8.6;

leave open if the sense comparator is not needed

not connected

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 9

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
