ISL88031IU8ECZ-TK

Supervisors Overview

The ISL88031IU8ECZ-TK is a quintuple voltage monitor integrated circuit manufactured by Renesas Electronics Corporation. It monitors up to five distinct supply voltages within a compact 8-lead MSOP surface-mount package. The device operates with a supply voltage range of 2 V to 5.5 V and features manual reset functionality without an integrated watchdog timer. It provides open-drain or open-collector outputs for each monitored channel, allowing flexible interface integration. The component is designed for industrial applications with an operating temperature range spanning from -40°C to +85°C.

Supervisors Feature Summary

• Monitors up to five independent voltage rails simultaneously
• Provides manual reset capability with open-drain/open-collector outputs
• Compact 8-lead MSOP surface-mount packaging for space-constrained designs

Supervisors Applications

• Industrial control systems requiring multi-rail power supervision
• Embedded systems monitoring multiple logic and analog supply voltages
• Automotive electronics utilizing robust voltage supervision in harsh environments

Supervisors Procurement Notes

Verify the specific suffix ECZ-TK against current Renesas documentation to confirm tape-and-reel packaging and exact threshold configurations. Confirm end-of-life status and lead time availability through authorized distributors, as this part may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints and design-in requirements before finalizing procurement plans.

Supervisors Selection Notes

Select this component when simultaneous monitoring of five distinct voltage levels is required in a minimal footprint. It is suitable for designs needing manual reset intervention rather than automatic watchdog recovery. Verify that the available threshold options meet the specific under-voltage and over-voltage trip points required by the target application's power architecture.

Supervisors Part Context

This part belongs to the ISL88031 series of voltage supervisors from Renesas (formerly Intersil). The series focuses on providing comprehensive power management supervision in small packages. Similar parts in the family may offer different numbers of monitored channels or additional features such as watchdog timers, but the ISL88031 specifically targets quintuple monitoring needs.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the ISL88031 family with different suffixes. Evaluate alternative quintuple supervisors from other manufacturers if supply constraints persist, ensuring electrical parameters like threshold accuracy and operating voltage ranges remain compatible.
