ISL88031IU8ECZ

Supervisors Overview

The ISL88031IU8ECZ is a quintuple voltage-monitoring supervisor from Renesas Electronics. It integrates five independent voltage monitoring channels with competitive reset threshold accuracy and low power consumption. The device operates within a supply voltage range of 2 V to 5.5 V and features manual reset functionality without an integrated watchdog timer. It utilizes an 8-MSOP surface-mount package and supports open-drain or open-collector outputs for system reset signaling.

Supervisors Feature Summary

• Integrates five independent voltage monitoring channels for comprehensive system supervision
• Provides manual reset capability with configurable threshold accuracy
• Designed for low power consumption in portable and battery-operated applications

Supervisors Applications

• Portable electronic devices requiring multi-voltage supervision
• Battery-powered systems needing low quiescent current monitoring
• Industrial control boards utilizing multiple logic supply rails

Supervisors Procurement Notes

Verify component authenticity through authorized Renesas distributors due to end-of-life status. Confirm package integrity and pin alignment against the 8-MSOP specification. Review datasheet revisions for any parameter updates prior to integration into new designs.

Supervisors Selection Notes

Select this component when five distinct voltage rails require simultaneous supervision. Ensure the application does not necessitate an internal watchdog timer, as this variant lacks that feature. Verify that the manual reset interface aligns with the target microcontroller or FPGA configuration requirements.

Supervisors Part Context

This part belongs to the ISL88031 series of voltage supervisors. It shares core architectural similarities with variants like the ISL88031IU8HCZ but differs in specific threshold configurations and packaging suffixes. The series targets cost-sensitive applications requiring reliable power management without complex digital interfaces.

Supervisors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the end-of-life status, direct replacements may require design adaptation or alternative supervisory ICs with similar channel counts.
