ISL88011IH531Z-T7A

Supervisors Overview

The ISL88011IH531Z-T7A is a single-channel voltage supervisor IC 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 4.64V for power monitoring. The device provides active-high and active-low reset outputs with a minimum reset timeout of 200ms. It supports manual reset functionality via an external pin. The component is housed in a 5-pin SOT-23 (SC-74A) surface-mount package and is rated for operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides reliable system reset generation through dual active-high and active-low output configurations.
• Integrates manual reset capability allowing external control over the reset state.
• Ensures stable operation with a defined reset timeout period to prevent premature system restarts.

Supervisors Applications

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

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific suffix matches the required threshold and package specifications. Check current production status as this part may be subject to obsolescence notices. Ensure storage conditions comply with moisture sensitivity level requirements before soldering.

Supervisors Selection Notes

Select this component when a single-channel supervisor with both active-high and active-low outputs is required. The 4.64V threshold suits applications monitoring standard 5V logic rails. Consider the manual reset feature if external system intervention is necessary. Verify that the SOT-23 package fits the available PCB footprint constraints.

Supervisors Part Context

This part belongs to the ISL8801x series of voltage supervisors from Renesas, formerly Intersil. The series offers various threshold voltages and output configurations tailored for different power rail monitoring needs. It complements Renesas' broader portfolio of power management integrated circuits designed for industrial and consumer electronics applications.
