ISL61852BIRZ-T

Hot Swap Controllers Overview

The ISL61852BIRZ-T 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 features an internal current output capability of up to 600mA with a supply current of 50 µA. The device is housed in an 8-DFN (3x3) package with a bare pad, suitable for surface mount installation. It supports an operating temperature range from -40°C to +85°C and includes built-in protection mechanisms such as automatic retry, fault timeout, thermal limiting, conduction voltage control, and under-voltage lockout.

Hot Swap Controllers Feature Summary

• Integrates two independent P-channel MOSFET power switches for dual-port USB hot swap control
• Provides comprehensive fault protection including overcurrent, thermal limiting, and under-voltage lockout
• Supports automatic retry functionality to manage transient faults without manual intervention

Hot Swap Controllers Applications

• Dual-port USB hub power management
• USB peripheral hot insertion and removal protection
• Portable device power distribution systems

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'BIRZ' against the manufacturer's latest datasheet to confirm pinout and electrical specifications match your design requirements. Ensure compatibility with the 8-DFN (3x3) footprint during PCB layout. Confirm RoHS3 compliance status if required by your assembly standards. Check for any recent Product Change Notifications regarding labeling or packaging updates before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component when designing circuits requiring independent overcurrent protection for two USB ports within a compact form factor. It is suitable for applications needing low quiescent current and robust fault handling features like thermal limiting and auto-retry. Consider the 8-DFN package constraints and ensure adequate thermal relief on the exposed pad for heat dissipation during operation.

Hot Swap Controllers Part Context

This part belongs to the ISL6185 family of USB power controllers, which provides fully independent overcurrent fault protection for multiple USB ports. The family offers various functional variants and package options, all rated for nominal +2.5V to +5V ranges. The ISL61852 variant specifically integrates two internal power switches, distinguishing it from single-channel or higher-density alternatives in the same series.
