ISL88003IE17Z-T

Supervisors Overview

The ISL88003IE17Z-T is a low-power voltage supervisor from the Renesas ISL88003 series, designed for monitoring single power supply rails. It features a fixed threshold of 1.67 V with ±1.2% accuracy and a push-pull reset output. The device operates within a supply range of 1.2 V to 2.75 V, consuming only 300 nA of quiescent current. It provides a 190 ms reset delay and functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low power consumption with minimal quiescent current draw
• High-precision voltage threshold monitoring with tight accuracy tolerance
• Push-pull output driver ensures robust signal integrity down to low voltages
• Compact surface-mount packaging minimizes board space requirements

Supervisors Applications

• Microprocessor and microcontroller system supervision
• Portable and battery-powered equipment
• Intelligent instruments and controllers
• Computer systems requiring reliable power-on reset

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance and moisture sensitivity level handling requirements during storage and assembly. Ensure replacement parts match original pinout and electrical specifications to maintain system reliability.

Supervisors Selection Notes

Select this supervisor when precise monitoring of low-voltage rails near 1.67 V is required. Consider the push-pull output capability if driving loads directly without external pull-ups. Evaluate the 300 nA current consumption against strict battery life requirements in portable designs.

Supervisors Part Context

Part of the ISL88003 family of ultra-low power voltage supervisors. Designed to replace legacy components like MAX803/MAX809 while offering improved accuracy and lower power consumption. Manufactured by Renesas Electronics Corporation under the Intersil brand heritage.

Supervisors Replacement Considerations

Pin-compatible alternatives include MAX803, MAX809, and MAX810 series devices. Verify threshold voltage compatibility before substitution to ensure correct reset timing relative to the monitored rail.
