ISL61852ICRZ

Hot Swap Controllers Overview

The ISL61852ICRZ is a dual-channel hot-swap voltage controller designed for USB applications, manufactured by Renesas Electronics Corporation. It integrates high-side N-channel MOSFETs within an 8-lead DFN package measuring 3x3 mm. The device operates with a supply voltage range of 2.3V to 5.5V and supports a maximum output current of 600mA per channel. It functions reliably across a commercial temperature range of 0°C to +70°C. Key electrical characteristics include a quiescent supply current of 50µA and integrated fault protection mechanisms such as thermal limiting and UVLO.

Hot Swap Controllers Procurement Notes

Verify the specific suffix IC against official Renesas documentation to confirm the commercial temperature rating and pinout configuration. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Check for end-of-life notifications or obsolescence notices from the manufacturer to ensure long-term availability for production cycles.

Hot Swap Controllers Selection Notes

Select this component when designing dual-channel USB power supplies requiring integrated switching elements. Ensure the application environment remains within the specified 0°C to +70°C operating range. Verify that the required load current does not exceed the 600mA limit per channel and that the system voltage stays within the 2.3V to 5.5V input specification.
