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