ISL88003IH31Z-T

Supervisors Overview

The ISL88003IH31Z-T is a low-power voltage supervisory circuit manufactured by Renesas Electronics. It monitors a single input voltage with an undervoltage threshold of 3.07 V and an overvoltage threshold of 3.112 V. The device features a push-pull active high reset output with a fixed delay time of 190 ms. It operates within a supply voltage range of 1.8 V to 5.5 V, consuming only 350 nA of operating supply current. Accuracy is specified at 1.2%. The component is housed in an SOT-23 package and supports surface mount installation. It functions without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Monitors single voltage input with precise threshold detection
• Provides active high push-pull reset signal generation
• Ultra-low power consumption for battery-operated applications

Supervisors Applications

• Portable electronic devices requiring voltage supervision
• Battery-powered systems needing low quiescent current monitoring
• Embedded circuits requiring reliable power-on reset signals

Supervisors Procurement Notes

Verify the specific suffix designation against official documentation, as variations may exist between tape-and-reel packaging formats. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the source document explicitly identifies this exact part number variant to avoid confusion with similar series components. Check for any recent product change notices affecting availability or specifications.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with push-pull output is required. Consider the 3.07 V threshold suitability for the target rail voltage. Evaluate the 190 ms reset delay against system startup timing requirements. Verify that the SOT-23 package fits the design constraints. Compare the 350 nA current draw against other options if ultra-low power is critical.
