ISL6144IR

Overview

The ISL6144IR is a dual-channel hot swap controller manufactured by Renesas (formerly Intersil). It operates within a supply voltage range of 10 V to 80 V and features a quiescent current of 900 uA. The device supports single-channel operation with power fail detection capabilities. It is designed for surface-mount installation in SOIC-8 packages, functioning reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel architecture for independent load management
• Integrated power fail detection mechanism
• Supports hot swap operations for safe insertion and removal

Applications

• Telecommunications equipment power distribution
• Industrial control system backplanes
• Server and storage array power modules

Procurement Notes

Verify the specific suffix 'IR' against official datasheets to confirm package type and temperature grade. Confirm availability status as distribution channels may list limited stock or end-of-life notices. Ensure RoHS compliance matches project requirements before procurement.

Selection Notes

Select this component when dual-channel isolation is required within a compact footprint. Verify that the input voltage does not exceed the 80 V maximum rating. Consider the SOIC-8 thermal performance for high-current applications.

Part Context

Part of the ISL614x family of hot swap controllers. Designed for systems requiring controlled power sequencing and protection against overcurrent conditions during module insertion.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio. Verify electrical parameter equivalence for voltage ratings and current limits.
