ISL88022IU8HEZ

Supervisors Overview

The ISL88022IU8HEZ is a voltage supervisor IC from the Intersil (Renesas) family, designed for monitoring multiple power rails. It features three monitored inputs with adjustable under-voltage and over-voltage thresholds. The device operates within a supply voltage range of 2 V to 5.5 V and supports an operating temperature range of -40°C to +85°C. It provides manual reset functionality and utilizes an MSOP-8 package for surface-mount installation.

Supervisors Feature Summary

• Monitors three independent voltage inputs simultaneously
• Features adjustable threshold voltages for custom trip points
• Includes manual reset capability for system control
• Operates with low quiescent current consumption

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Voltage supervision for portable electronic devices
• Industrial control board power integrity verification

Supervisors Procurement Notes

Verify component authenticity due to potential availability from secondary markets. Confirm RoHS compliance status through official documentation. Check for end-of-life notifications or discontinuation notices from Renesas Electronics. Ensure packaging type matches design requirements. Validate date codes against project timelines.

Supervisors Selection Notes

Select this component when three-channel voltage monitoring is required with adjustable thresholds. Consider the MSOP-8 package size for space-constrained designs. Verify that the input voltage range covers all monitored rails. Ensure compatibility with system reset logic requirements.

Supervisors Part Context

Part of the ISL8802x series of voltage supervisors from Intersil, now part of Renesas Electronics. This series offers compact solutions for multi-voltage monitoring applications. The ISL88022 variant specifically provides three monitored channels with flexible threshold settings.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the ISL8802x family. Verify functional equivalence for threshold adjustability and reset behavior. Consult Renesas documentation for updated alternatives if discontinued.
