ISL61852BIRZ

Hot Swap Controllers Overview

The ISL61852BIRZ is a dual-channel hot swap voltage controller designed for USB applications, manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.3V to 5.5V and features an internal current limit of 600mA per channel. The device supports automatic retry and fault timeout functions, with a quiescent supply current of 50µA. It is housed in an 8-VDFN package with a bare pad, measuring 3x3mm, and is rated for operation between -40°C and +85°C.

Hot Swap Controllers Feature Summary

• Dual independent channels provide fully independent overcurrent fault protection for multiple USB ports.
• Integrates two P-channel MOSFET power switches for direct power control within a single package.
• Includes internal current monitoring and accurate current limiting capabilities for precise load management.

Hot Swap Controllers Applications

• USB port power supply controllers
• Hot swap voltage control systems
• Multi-port USB hub power management

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'BIRZ' against the manufacturer's official datasheet to confirm pinout compatibility and functional specifications. Ensure the component meets RoHS3 compliance requirements if mandated by your design standards. Confirm that the 8-DFN package dimensions align with your PCB footprint constraints before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this component when designing circuits requiring independent overcurrent protection for multiple USB interfaces. The integrated MOSFETs simplify board layout by reducing external component count. Consider the 50µA supply current for low-power standby applications and verify that the 600mA output capability matches the maximum load requirements of the connected USB devices.

Hot Swap Controllers Part Context

The ISL61852BIRZ belongs to the ISL6185XXI family of dual USB port power supply controllers. This family provides sixteen individual functional variants across three package options, all rated for nominal +2.5V to +5V ranges. The series is specified for both commercial and industrial temperature environments, ensuring reliability in diverse operational conditions.
