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 referenceand a comparatorwith opendrain output. The threshold voltage is set at 4.33V by internal thermally matched resistors.
The comparator of the TS834 exhibits a 20ms response (with 10mV overdrive).
An internalhysteresisof 100mVincreases thecomparator noise margin and prevents false reset
