1 / 7 page 1/7 s ULTRA LOW POWER CONSUMPTION : 12 µA max. @ V CC = 5V s BOTH ACTIVE HIGH AND ACTIVE LOW OUTPUTS s RESET TIMER WITH DISABLE FUNCTION s PRECISION RESET THRESHOLD (guaran- teed over Temperature) s 4.33V typ. THRESHOLD VOLTAGE s GUARANTEED RESET OPERATION DOWN TO 1.5V s OPEN DRAIN OUTPUT WITH s Vol = 450mV typ.@ Iol = 8mA & V CC = 4V s FAST RESPONSE TIME : 20 µs FOR A 10mV OVERDRIVE s 100mV 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 dis- abled. It incorporates a high stability bandgap voltage reference and a comparator with open drain out- put. The threshold voltage is set at 4.33V by internal thermally matched resistors. The comparator exhibits a 20 µs response (with 10mV overdrive). An internal hysteresis of 100mV increases the comparator noise margin and prevents false reset operation.
