DESCRIPTION
The TS831 is an ultra low power integrated circuit
incorporating a high stability band-gap voltage
reference and a comparator with an open drain
output.
The threshold voltage is set at 4.33V for TS831-5,
4.5V for TS831-4 and 2.71V for TS831-3 by
internal thermally matched resistors.
The comparator exhibits a 20µs response (with
10mV overdrive) and has an open drain output
active when input voltage is lower than the
threshold. An internal hysteresis, 100mV for
TS831-4 / TS831-5 and 60mV for TS831-3,
increases the comparator’s noise margin and
prevents false reset operation.
