ISL88003IE23Z-T7A

Supervisors Overview

The ISL88003IE23Z-T7A is a voltage supervisory circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 1.8 V to 5.5 V and features a threshold voltage of 2.32 V with an accuracy of 1.2%. The device provides a push-pull reset output with a fixed reset delay time of 190 ms. It consumes a typical operating supply current of 350 nA and includes an overvoltage threshold of 2.662 V. The component is housed in an SOT-23 package and supports surface mount installation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides low-power voltage supervision for single-input monitoring applications
• Delivers active high push-pull reset signal without manual reset capability
• Ensures precise voltage tracking with specified accuracy and defined reset timing

Supervisors Applications

• Industrial control systems requiring power management
• Embedded electronics needing simple reset generation
• Portable devices utilizing low standby current requirements

Supervisors Procurement Notes

Verify the specific suffix Z-T7A against official Renesas documentation to confirm tape and reel packaging details. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Check for end-of-life notices or product change notifications prior to final design approval. Ensure the SOT-23 footprint matches your PCB layout constraints exactly.

Supervisors Selection Notes

Select this component when a fixed threshold near 2.32 V is required for system monitoring. The push-pull output eliminates the need for external pull-up resistors compared to open-drain alternatives. Consider the 190 ms reset delay to ensure adequate stabilization time for downstream logic. Verify that the 350 nA quiescent current meets the strict power budget of the target application.

Supervisors Part Context

This part belongs to the ISL88003 series of voltage supervisors from Renesas, formerly Intersil. The series offers various threshold options packaged in compact forms like SOT-23 and SC-70. These components are designed for general-purpose power management tasks where reliable reset signaling is critical for system stability and data integrity during power transitions.
