ISL88022IU8HEZ

Supervisors Overview

The ISL88022IU8HEZ is a synchronous buck controller manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2 V to 5.5 V and features an MSOP-8 surface-mount package. The device monitors five distinct input voltages with adjustable thresholds, including specific overvoltage limits at 4.717 V, 3.008 V, and 611 mV, alongside under-voltage thresholds at 4.551 V, 2.901 V, and 589 mV. It draws a typical operating current of 19 uA and functions reliably across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Supports simultaneous monitoring of five independent voltage inputs
• Provides manual reset functionality for system recovery
• Features adjustable threshold detection for flexible configuration

Supervisors Applications
