ISL61852HCRZ

Hot Swap Controllers Overview

The ISL61852HCRZ is a dual-channel hot swap voltage controller designed for USB applications. 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 functionality, fault timeout protection, thermal limiting, and under-voltage lockout (UVLO). It is housed in an 8-lead DFN package measuring 3x3 mm with an exposed pad for enhanced thermal dissipation.

Hot Swap Controllers Feature Summary

• Dual-channel architecture for independent USB port control
• Integrated thermal limiting and fault timeout protection
• Automatic retry capability for transient fault recovery

Hot Swap Controllers Applications

• USB hub power distribution
• Peripheral card insertion systems
• Hot-swappable backplane interfaces

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm the specific suffix 'H' corresponds to the required temperature grade and packaging format. Check for End-of-Life notifications as discontinuance may affect long-term availability. Ensure compliance with RoHS directives relevant to your target market before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this controller when dual-channel USB hot swap protection is required in a compact footprint. Consider the 600mA internal switch rating against maximum load requirements. Evaluate the 3x3mm DFN package suitability for PCB space constraints. Verify that the operating temperature range meets environmental specifications for the intended deployment scenario.
