ISL88031IU8EAZ-TK

Supervisors Overview

The ISL88031IU8EAZ-TK is a quintuple voltage-monitoring supervisor from Renesas Electronics. It integrates five independent voltage monitors with manual reset functionality in an 8-MSOP package. The device operates within a supply voltage range of 2V to 5.5V and supports monitoring inputs with specific threshold configurations, such as Vtrip1 at 2.90V for the EAZ variant. It features low power consumption and competitive reset threshold accuracy. The component is designed for surface mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates five independent voltage monitoring channels for comprehensive system supervision
• Provides manual reset capability with open-drain or open-collector output structure
• Delivers competitive reset threshold accuracy combined with low power consumption characteristics

Supervisors Applications

• Multi-rail power supply monitoring in industrial equipment
• Voltage supervision for embedded systems requiring multiple logic levels
• System integrity monitoring in consumer electronics with complex power architectures

Supervisors Procurement Notes

Verify current availability status as this part number may be subject to end-of-life restrictions or discontinuation notices from the manufacturer. Confirm that the tape-and-reel packaging format matches your automated assembly requirements. Ensure compatibility with existing PCB footprints and design-in documentation before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single IC solution is required to monitor five distinct voltage rails simultaneously. It is suitable for designs needing precise threshold detection without external comparator components. Consider the 8-MSOP package constraints and thermal performance limits when integrating into dense circuit layouts.

Supervisors Part Context

This supervisor belongs to the ISL88031 family of multi-channel voltage monitors. The suffix EA-Z indicates specific factory-set threshold voltages for the monitored inputs. The TK suffix denotes the tape-and-reel packaging configuration intended for high-volume automated placement processes.

Supervisors Replacement Considerations

Direct substitutes include other variants within the ISL88031 series with different threshold settings, such as ISL88031IU8HFZ. Verify pinout compatibility and electrical specifications before substitution.
