Quintuple Voltage Monitor
The ISL88031 is a quintuple voltage-monitoring supervisor
combining competitive reset threshold accuracy and low
power consumption. This device combines popular functions
such as Power-On Reset, Undervoltage Supply Supervision,
reset signaling and Manual Reset. Monitoring up to five
different voltages in a small 8 Ld MSOP package, the
ISL88031 devices can help to lower system cost, reduce
board space requirements, and increase the reliability of
multi-voltage systems.
Low V DD detection circuitry protects the user ’s system from
low voltage conditions, resetting the system when V DD or
any of the other monitored power supply voltages fall below
their respective minimum voltage thresholds. The reset
signal remains asserted until all of these voltages return to
proper operating levels and stabilize.
With two of the five voltage monitors being preset for
common supplies, users can adjust the threshold voltages of
the third, fourth, and fifth voltage monitors in order to meet
specific system level requirements.
