... Data Sheet 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 ...

... V , V2MON and V3MON. The DD ISL88021 asserts reset if any one of these voltages fall below their respective voltage trip points and in the case of ISL88022 above the voltage trip point on the V3MON input. The reset signal effectively prevents the microprocessor from operating during a power failure, brownout or over voltage condition ...

... Both ICs are the ‘HF’ variant having a V V2MON Vth of 3.09V and V3MON Vth of 0.6V. The top IC position is the ISL88021 and is configured to monitor for undervoltage (UV) compliance of a 5V, 3.3V and a 2.5V and signaling the RESET and RESET outputs. The bottom position is the ISL88022 variant, which is configured to measure a 3 ...
