DESCRIPTION

The TS831 ultra low power integrated circuit incor-

porates a high stability band-gap voltage refer-

ence and a comparator with open drain output.

The threshold voltage is set at 4.33V for TS831-5,

4.5V for TS831-4 and 2.71V for TS831-3 by inter-

nal thermally matched resistances.

TSSOP-8

(Thin Shrink Small Outline Package)

The comparator exhibits a 20µs response (with

10mV overdrive) and has an open drain output ac-

tive when input voltage is lower than the threshold.

An internal hysteresis, 100mV for TS831-4/

TS831-5 and 60mV for TS831-3, increases the

comparator’s noise margin and prevents false re-

set operation.
