ISL61852CIRZ

Hot Swap Controllers Overview

The ISL61852CIRZ is a dual-channel hot-swap controller designed for USB applications, manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.3V to 5.5V and supports an internal switch configuration with a maximum output current of 600mA per channel. The device functions reliably across a commercial temperature range of -40°C to +85°C and consumes a typical supply current of 50µA. Packaged in an 8-lead DFN (3x3mm) format with an exposed pad, it integrates features such as automatic retry, fault timeout, thermal limiting, and undervoltage lockout.

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'C' against official Renesas documentation to confirm the exact temperature grade and package variant, as suffixes define critical environmental and physical specifications. Confirm component availability status, as this part number may be subject to discontinuation or lifecycle changes. Ensure compatibility with your system's voltage levels and thermal requirements before procurement.

Hot Swap Controllers Selection Notes

Select this component when designing dual-channel USB power solutions requiring integrated switching capabilities. It is suitable for applications needing precise overcurrent protection and thermal management without external discrete components. Consider the 8-DFN package constraints for PCB layout and thermal dissipation needs relative to the expected load currents.
