TO 1.5V s OPEN DRAIN OUTPUT WITH s Vol = 450m V typ.@ Iol = 8m A & VCC = 4V s FAST RESPONSE TIME : 20µs FOR A 10m V
OVERDRIVE s 100m V INTERNAL HYSTERESIS
DESCRIPTION
The TS834 is a voltage supervisor providing two different outputs (one active low and one active high) with an integrated timer that can be disabled.
It incorporates a high stability bandgap voltage reference and a parator with open drain output.
The threshold voltage is set at 4.33V by internal thermally matched resistors.
The parator exhibits a 20µs response (with 10m V overdrive).
An internal hysteresis of 100m V increases the parator noise margin and prevents false reset operation.
