ISL61851DIBZ

Hot Swap Controllers Overview

The ISL61851DIBZ is a dual-channel hot swap voltage controller designed for USB applications. It integrates two P-channel MOSFET power switches within an 8-SOIC package. The device operates with a supply voltage range of 2.3V to 5.5V and features a maximum output current capability of 600mA per channel. It includes internal fault protection mechanisms such as fault timeout, auto retry, and thermal limiting. The component supports surface mount installation and functions within an operating temperature range of 0°C to 70°C.

Hot Swap Controllers Procurement Notes

Verify the specific suffix DIBZ against official Renesas documentation to confirm package type and tape/reel configuration. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for end-of-life notifications or product change notices that may affect long-term availability or manufacturing parameters.

Hot Swap Controllers Selection Notes

Select this component when dual-channel hot swap functionality with integrated switches is required for USB interfaces. Ensure the 8-SOIC package fits the PCB layout constraints. Verify that the 2.3V to 5.5V supply range matches the system voltage rails. Consider the thermal performance limits if high load currents are expected in enclosed environments.
