ISL61861AIBZ-T7A

Hot Swap Controllers Overview

The ISL61861AIBZ-T7A is a dual-channel hot swap voltage controller designed for USB applications, manufactured by Renesas Electronics Corporation. It integrates internal power FETs with a maximum continuous current rating of 1.5 A per channel. The device operates within a supply voltage range of 2.5 V to 5.5 V and features a typical supply current of 57 µA. It supports an operating temperature range from -40°C to +85°C and is housed in an 8-SOIC package.

Hot Swap Controllers Feature Summary

• Integrates dual internal power FETs for compact single-chip hot swap control
• Provides comprehensive protection including fault timeout, latch-off, and thermal limiting
• Supports USB application requirements with integrated undervoltage lockout

Hot Swap Controllers Applications

• USB port protection and control
• Hot swap circuitry for peripheral devices
• Power management in USB host or hub systems

Hot Swap Controllers Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Verification of availability should be restricted to authorized distributors or secondary market sources. Confirm RoHS compliance status and moisture sensitivity level (MSL 2) prior to procurement. Ensure that any substitute components maintain equivalent electrical characteristics and pin compatibility.

Hot Swap Controllers Selection Notes

Select this part for designs requiring dual-channel hot swap control with integrated switches. Verify that the required current does not exceed the 1.5 A limit per channel. Consider the 8-SOIC package constraints for PCB layout. Evaluate alternative models within the ISL61861 series if different current ratings or retry features are needed.

Hot Swap Controllers Part Context

The ISL61861AIBZ-T7A belongs to the ISL6186XXC series of hot swap controllers. It is part of Renesas' portfolio of power management ICs focused on protecting downstream circuits during insertion and removal events. This specific variant includes the 'T7A' suffix indicating tape and reel packaging.

Hot Swap Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation due to the product's end-of-life status. Engineers must perform independent cross-referencing to identify compatible alternatives.
