ISL88001IE22Z-T7A

Supervisors Overview

The ISL88001IE22Z-T7A is a single-channel voltage supervisor integrated circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 1.6V to 5.5V and features a fixed threshold voltage of 2.23V for monitoring power rails. The device provides an active-low reset signal with a minimum timeout period of 140ms to ensure system stability during power transitions. Designed for surface-mount installation, it utilizes the compact SC-70 (SOT-323) three-terminal package. The component supports a wide operating temperature range from -40°C to +85°C and complies with RoHS3 standards.

Supervisors Feature Summary

• Provides reliable system reset generation via push-pull/totem pole output architecture
• Ensures stable operation through defined power-on reset timing characteristics
• Optimized for low-power applications with minimal quiescent current consumption

Supervisors Applications

• Industrial control systems requiring voltage supervision
• Portable battery-powered electronic devices
• Embedded microcontroller reset circuits

Supervisors Procurement Notes

Verify the specific suffix 'IE22' corresponds to the required 2.23V threshold voltage before procurement. Confirm package availability in SC-70-3 format. Check current lifecycle status as older Intersil/Renesas parts may have limited stock or obsolescence notices. Ensure compatibility with existing PCB footprint designs utilizing SOT-323 packages.

Supervisors Selection Notes

Select this component when a fixed 2.23V monitoring threshold is required for single-rail supervision. Compare against the ISL88002 series if open-drain outputs are preferred over push-pull configurations. Consider the ISL88001IE17Z variant if a lower 1.67V threshold better suits the target application voltage levels. Verify that the 140ms minimum reset delay meets the system's startup timing requirements.

Supervisors Part Context

This part belongs to the ISL88001/02/03 family of simple voltage supervisors originally developed by Intersil and now managed by Renesas. These components are designed for basic power management tasks where complex programmable features are unnecessary. The family offers various threshold options and output types to accommodate diverse embedded design constraints across consumer and industrial sectors.

Supervisors Replacement Considerations

ISL88001IE22Z-T is listed as a potential alternative within the same manufacturer lineup.
