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 20µs response (with
10mV overdrive).
An internal hysteresis of 100mV increases the
comparator noise margin and prevents false reset
operation.
