ISL88003IE31Z-T7A

Supervisors Overview

The ISL88003IE31Z-T7A is a voltage supervisory circuit manufactured by Renesas Electronics Corporation. It monitors a single input voltage with a threshold of 3.09 V and an overvoltage threshold of 3.124 V. The device features a push-pull output type and provides a reset delay time of 190 ms. It operates within a supply voltage range of 1.8 V to 5.5 V and maintains an accuracy of 1.2%. The component consumes a working power supply current of 350 nA and functions reliably across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage supervision for single-input systems with high accuracy.
• Features low quiescent current consumption suitable for battery-powered applications.
• Delivers active-high push-pull reset signals for robust interface compatibility.

Supervisors Applications

• Industrial control system power monitoring
• Portable electronic device voltage supervision
• Embedded system power management

Supervisors Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations may affect package or electrical characteristics. Confirm availability status through authorized channels due to potential lifecycle changes. Ensure compliance with RoHS directives and moisture sensitivity levels specified in the manufacturer documentation before integration into production designs.

Supervisors Selection Notes

Select this component when a fixed 3.09 V threshold is required for single-channel supervision. Consider the SC-70-3 package constraints and push-pull output requirements. Evaluate the 190 ms reset delay against system startup timing needs. Verify that the 1.2% accuracy meets the specific application tolerance requirements.

Supervisors Part Context

This part belongs to the ISL88003 series of voltage supervisors from Renesas. The series offers various threshold voltages and packages to suit different monitoring needs. The IE31 variant specifically targets applications requiring a 3.09 V trip point in a compact surface-mount package.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the ISL88003 family with adjusted thresholds. Verify functional equivalence regarding output drive capability and reset delay times before substitution.
