ISL88031IU8EAZ

Supervisors Overview

The ISL88031IU8EAZ is a five-channel voltage supervisory circuit manufactured by Renesas Electronics Corporation. It monitors multiple power rails within a system to ensure stable operation. The device operates with a supply voltage range of 2 V to 5.5 V and draws a typical operating supply current of 19 uA. It features adjustable undervoltage and overvoltage thresholds, allowing for customized monitoring levels. The IC provides manual reset functionality and utilizes an open-drain or open-collector output configuration. It is housed in an 8-MSOP surface-mount package and supports an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Monitors up to five independent voltage inputs simultaneously
• Features adjustable threshold voltages for flexible system integration
• Includes manual reset capability for controlled system recovery
• Utilizes low-power architecture suitable for battery-operated applications

Supervisors Applications

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

Supervisors Procurement Notes

Verify component authenticity through authorized channels as the part is listed as obsolete. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for available stock from secondary distributors if immediate availability is required. Ensure packaging specifications match storage requirements to prevent damage due to humidity exposure during handling and assembly processes.

Supervisors Selection Notes

Select this component when multi-channel voltage supervision is required without watchdog timer functionality. Consider the 8-MSOP package size for space-constrained designs. Verify that the adjustable threshold ranges meet specific rail monitoring needs. Evaluate the low quiescent current against total system power budget constraints. Ensure compatibility with the target operating temperature range for the intended application environment.

Supervisors Part Context

This component belongs to the ISL88031 series of voltage supervisors. It shares functional similarities with other parts in the family but offers specific channel counts and package options. The series is designed for general-purpose power monitoring tasks. Renesas Electronics continues to support legacy components through documentation updates despite end-of-life status.
