Quad Voltage Monitor

The ISL88041 is a quad voltage-monitoring supervisor designed to monitor voltages ≥0.7V. Low voltage detection circuitry protects the user s system from low voltage conditions, resetting the system when any of the monitored power supply voltages V1MON-V4MON fall below their respective minimum voltage thresholds. The reset signal remains asserted until all of these voltages return to proper operating levels and stabilize.
