ISL61852FIRZ

Hot Swap Controllers Overview

The ISL61852FIRZ 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 supports an output current up to 600mA per channel. The device features internal switches and functions including automatic retry, fault timeout, thermal limiting, conduction voltage control, and UVLO. It is housed in an 8-VDFN package with a bare pad (3x3mm) and operates across a temperature range of -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Dual-channel architecture for independent USB port power management
• Integrated internal FETs eliminate external switch requirements
• Comprehensive protection mechanisms including thermal limiting and fault timeouts

Hot Swap Controllers Applications

• USB hub power distribution
• Peripheral device hot insertion
• System board power sequencing

Hot Swap Controllers Procurement Notes

Verify component status as the ISL61852 series may be discontinued or subject to production discontinuance notifications. Confirm availability through authorized distributors and check for last-time buy options if required for long-term manufacturing support.

Hot Swap Controllers Selection Notes

Select this component for designs requiring integrated dual-channel hot swap control without external pass transistors. Ensure the 8-DFN thermal performance meets system dissipation requirements. Verify that the 2.3V to 5.5V input range aligns with the target bus voltage specifications.

Hot Swap Controllers Part Context

Part of the ISL6185XXI family of hot swap controllers from Renesas/Intersil. This specific variant targets commercial and industrial temperature ranges with a compact DFN footprint suitable for space-constrained portable and desktop electronics.

Hot Swap Controllers Replacement Considerations

Check for direct pin-compatible substitutes within the ISL61852 series such as ISL61852EIRZ or ISL61852ICRZ, noting potential differences in temperature ratings or packaging. Evaluate newer Renesas PMIC families for functional equivalents if the legacy part is unavailable.
