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 ref-

erence and a comparator with open drain output.

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.
