TS834(1999) Datasheet PDF - STMicroelectronics

DESCRIPTION
The TS834 is a voltage supervisor providing two different outputs (one active low and one active high) with anintegrated timer that can bedisabled. It incorporates a high stability bandgap voltage reference and a comparator with open drain output. The threshold voltage is set at 4.33V by internal thermally matched resistors.
The comparator exhibits a 20µs response (with 10mV overdrive).
An internal hysteresis of 100mV increases the comparator noisemargin and preventsfalsereset operation.
