ISL88002IH22Z-TK

Supervisors Overview

The ISL88002IH22Z-TK is an ultra-low power voltage supervisor from Renesas, designed for monitoring single power supply rails. It operates within a supply voltage range of 1.8 V to 5.5 V and features a fixed threshold of 2.19 V with a reset delay of 190 ms. The device provides an active low open-drain output and maintains high accuracy of 1.2%. It consumes only 350 nA of quiescent current and functions reliably across temperatures from -40°C to +85°C in a compact SOT-23-3 package.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Fixed threshold voltage monitoring for precise power supervision
• Active low open-drain reset output compatible with various logic levels

Supervisors Applications

• Portable electronic devices requiring extended battery life
• Embedded systems needing reliable power-on reset generation
• Industrial control units operating in wide temperature ranges

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance and moisture sensitivity level before storage. Check for specific datasheet revisions affecting electrical characteristics. Ensure proper handling procedures are followed during assembly to prevent electrostatic discharge damage.

Supervisors Selection Notes

Select this component when fixed threshold monitoring is required without programmability needs. Consider the SOT-23-3 package constraints for space-limited designs. Evaluate the 190 ms reset delay against system startup timing requirements. Compare quiescent current specifications against other supervisors in the same family for optimal efficiency.
