DESCRIPTION
The TS836ultra lowpowerintegratedcircuitincorporates ahigh stabilityband gap voltagereference
and a comparatorwith open drain output.
The thresholdvoltageisset at 4.5Vfor TS836-4by
internal thermally matched resistances.
The comparator exhibits a 20µs response (with
10mV overdrive) and has an open drain output
activewhen inputvoltageishigher thanthethreshold.
An internalhysteresisof100mVincreasesthecomparator’s noise margin and prevents false reset
operation.
