ISL61852DCRZ

Hot Swap Controllers Overview

The ISL61852DCRZ is a dual-channel hot-swap controller designed for USB applications, manufactured by Renesas Electronics Corporation. It integrates internal low-side switches and operates within a supply voltage range of 2.3V to 5.5V. The device supports a maximum output current of 600mA per channel and features an operating temperature range from -40°C to 85°C. It utilizes an 8-DFN (3x3) package with exposed pad for surface-mount installation.

Hot Swap Controllers Feature Summary

• Dual-channel architecture with integrated internal low-side switches for compact design
• Comprehensive protection mechanisms including fault timeout, thermal limiting, and undervoltage lockout
• Automatic retry functionality to manage transient faults without manual intervention

Hot Swap Controllers Applications

• USB peripheral hot-plugging systems
• Industrial control board power management
• Telecommunications equipment interface protection

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm package marking and datasheet revision match the specific lot code. Request RoHS compliance documentation and moisture sensitivity level certification prior to procurement to ensure assembly reliability.

Hot Swap Controllers Selection Notes

Select this component for designs requiring dual independent channel protection in space-constrained environments. Ensure input voltage stays within the 2.3V to 5.5V range. Verify that the 600mA current limit aligns with load requirements. Consider the 8-DFN thermal performance for adequate heat dissipation in high-density layouts.

Hot Swap Controllers Part Context

This part belongs to the ISL61852 family of hot-swap controllers, which are optimized for USB interfaces. It succeeds earlier Intersil designs under the Renesas portfolio. The DCRZ suffix indicates a specific tape-and-reel packaging variant suitable for automated surface-mount assembly processes.

Hot Swap Controllers Replacement Considerations

Public confirmed substitutes include ISL61852ICRZ and ISL61852FIRZ. These variants share identical electrical specifications and pinouts but differ in packaging or reel configuration. Verify compatibility with existing PCB footprints before substitution.
