ISL88031IU8HFZ

Supervisors Overview

The ISL88031IU8HFZ is a quintuple voltage monitor IC manufactured by Renesas Electronics Corporation. It features five independent monitoring channels with adjustable under-voltage and over-voltage thresholds, including specific fixed thresholds of 4.551 V, 2.901 V, and 589 mV for under-voltage, and 4.717 V, 3.008 V, and 611 mV for over-voltage. The device operates within a supply voltage range of 2 V to 5.5 V and consumes a typical quiescent current of 19 uA. It provides manual reset functionality and utilizes an 8-lead MSOP package suitable for surface-mount applications.

Supervisors Feature Summary

• Provides simultaneous supervision of five distinct voltage rails with configurable threshold levels.
• Integrates manual reset capability for controlled system recovery without watchdog timer dependency.
• Operates with ultra-low power consumption suitable for battery-sensitive or energy-efficient designs.

Supervisors Applications

• Multi-rail power supply monitoring in industrial control systems
• Voltage supervision for embedded computing platforms
• Power management units requiring manual reset logic

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level handling requirements during storage and assembly. Check for recent product change notifications affecting pinout or electrical characteristics before finalizing procurement plans.

Supervisors Selection Notes

Select this component when multi-channel voltage supervision with manual reset is required. Ensure input voltages remain within the 2 V to 5.5 V operating range. Consider the MSOP-8 package constraints for PCB layout. Verify that adjustable thresholds meet specific circuit requirements compared to fixed-threshold alternatives.

Supervisors Part Context
