Triple Voltage Monitor with Adjustable Power-On-Reset and Undervoltage/Overvoltage Monitoring Capability

The ISL88021 and ISL88022 family of devices are customizable triple voltage-monitoring supervisors that assert a reset if any of the monitored voltages becomes non-compliant. They offer popular functions such as Power-On-Reset timing control with both RESET and RESET outputs, Supply Voltage Supervision, both under or overvoltage detection, and Manual Reset assertion. By offering these features in a small 8 Ld MSOP package, the ISL88021 and ISL88022 can lower system cost, reduce board space requirements and increase the reliability of systems.
