ISL61863IIRZ

Hot Swap Controllers Overview

The ISL61863IIRZ is a single-channel hot swap voltage controller designed for USB applications. It operates within a supply voltage range of 2.5V to 5.5V and supports a maximum output current of 6A. The device features an internal switch and is housed in a 10-lead DFN package (DFN-EP-10). It functions across an industrial temperature range from -40°C to +85°C. Key electrical characteristics include a quiescent supply current of 57 µA. The component integrates protection mechanisms such as undervoltage lockout, fault timeout, and thermal limiting.

Hot Swap Controllers Feature Summary

• Integrates a single high-current internal switch for direct load connection
• Provides comprehensive protection against overcurrent, short circuits, and thermal events
• Supports automatic retry functionality following fault conditions
• Enables precise control of turn-on slew rate to minimize bus transients

Hot Swap Controllers Applications

• USB port power management and protection
• Hot swap insertion and removal for peripheral devices
• Industrial equipment requiring robust power sequencing
• Telecommunications infrastructure power distribution

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'IIRZ' corresponds to the industrial temperature grade (-40°C to +85°C) and tape/reel packaging configuration. Confirm that the manufacturer has not issued a discontinuance notification or product change notice affecting this specific variant. Ensure compatibility with existing PCB footprints and thermal requirements for the DFN-EP-10 package before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component when a single-channel solution with high current capability up to 6A is required for USB hot swap applications. It is suitable for designs needing integrated protection without external MOSFETs. Consider the industrial temperature range if operating environments exceed commercial limits. Evaluate the 10-lead DFN package size against available board space constraints.

Hot Swap Controllers Part Context

This part belongs to the ISL6186XXI series of hot swap controllers from Renesas Electronics Corporation. It complements other variants like the ISL61863AIRZ, which typically covers the commercial temperature range. The series provides standardized solutions for managing power insertion events in systems requiring reliable and protected power delivery.

Hot Swap Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin-to-pin compatibility and parameter equivalence with any potential alternative components from other manufacturers before implementation.
