ISL88003IE31Z-TK

Supervisors Overview

The ISL88003IE31Z-TK is an ultra-low power voltage supervisor from the Renesas ISL88003 series, designed for monitoring single-channel supply voltages. It features a push-pull active low output and operates within a supply voltage range of 1.8 V to 5.5 V. The device provides precise threshold detection with a typical under-voltage trip point of 3.038 V and an over-voltage trip point of 3.112 V. It includes a fixed reset delay time of 190 ms and maintains high accuracy of 1.2%. Operating current is minimized at 160 nA, ensuring efficient performance in battery-powered applications across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low quiescent current consumption of 160 nA for extended battery life
• Push-pull active low output driver for robust signal integrity
• High precision voltage monitoring with 1.2% accuracy
• Compact SC-70-3 surface-mount package design

Supervisors Applications

• Portable electronic devices requiring low standby power
• Battery-operated systems needing reliable voltage supervision
• Embedded circuits with strict space constraints

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'TK' indicates tape-and-reel packaging if required for automated assembly. Check for recent Product Change Notices regarding datasheet updates or manufacturing site changes. Ensure compliance with RoHS directives as indicated in official documentation. Validate lead-free status and humidity sensitivity classification prior to storage and handling.

Supervisors Selection Notes

Select this component when ultra-low current consumption is critical for system efficiency. The fixed 190 ms reset delay suits applications where immediate response is not mandatory. Verify that the 3.09 V nominal threshold aligns with the monitored rail's acceptable operating window. Consider the SC-70-3 package size against available PCB real estate. Ensure the operating temperature range meets the environmental requirements of the final deployment scenario.

Supervisors Part Context

This part belongs to the ISL88003 family of single-channel voltage supervisors manufactured by Renesas Electronics. The series focuses on providing precise monitoring solutions with minimal power overhead. These components are commonly integrated into power management subsystems where reliability and low energy usage are prioritized over complex programmability features.

Supervisors Replacement Considerations

Cross-reference with other ISL88003 variants sharing identical electrical characteristics and pinout configurations. Verify package compatibility before substitution. Consult official replacement lists for any discontinued or obsolescence notices.
