DESCRIPTION

The TS836 ultra low power integrated circuit incor-

porates a high stability band gap voltage reference

and a comparator with open drain output.

The threshold voltage is set at 4.5V for TS836-4 by

internal thermally matched resistances.

The comparator exhibits a 20

µs response (with

10mV overdrive) and has an open drain output

active when input voltage is higher than the thresh-

old.

An internalhysteresis of 100mV increases the com-

parator’s noise margin and prevents false reset

operation.

APPLICATIONS

Power-on reset generator for microcontroler
