Function

Input

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

recommended

Inhibit

enables/disables the device;

connect to I if the this function is not needed

Reset Output

open-collector output connected to the output via an internal 30kΩ pull-up resistor;

leave open if the this function is not needed

Ground

Reset Delay Timing

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

trigger time;

leave open if this function is not needed

Reset Threshold Adjust

connect an external voltage divider to adjust the reset switching threshold;

connect to GND for using internal threshold

Watchdog

rising edge triggered input for monitoring a microcontroller;

connect to GND if this function is not needed

Output

block to ground with a capacitor close to the IC terminals with a capacitance value

C ≥ 22 µF, and an ESR ≤ 3 Ω

Exposed Pad

attach the exposed pad on package bottom to the heatsink area on circuit board;

connect to GND
