ISL6151IB

Hot Swap Controllers Overview

The ISL6151IB is a dual-channel hot swap voltage controller designed for USB power applications. It provides fully independent overcurrent fault protection for two or more ports within a nominal +2.5V to +5V operating range. The device integrates two P-channel MOSFET power switches, each with an on-resistance of 71mΩ, into a single package. It features internal current monitoring and accurate current limiting capabilities. The component is specified for operation across full commercial and industrial temperature ranges.

Hot Swap Controllers Feature Summary

• Dual-channel architecture providing independent overcurrent protection for multiple USB ports
• Integrated dual P-channel MOSFET power switches for efficient power control
• Internal current monitoring with accurate current limiting functionality
• Operates within a nominal +2.5V to +5V supply voltage range

Hot Swap Controllers Applications

• USB port power management systems
• Hot swap voltage control in peripheral devices
• Multi-port USB hub power distribution

Hot Swap Controllers Procurement Notes

Verify the specific suffix (e.g., IB vs IZ) against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status as it varies by manufacturing date code. Check for product discontinuance notifications from Renesas Electronics, as Intersil products are subject to legacy lifecycle management. Ensure the source document explicitly lists the ISL6151IB part number to avoid confusion with similar variants in the ISL6185 family.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring independent overcurrent protection for dual USB ports. The integrated P-channel MOSFETs simplify the bill of materials compared to discrete solutions. Verify that the required operating voltage falls within the +2.5V to +5V range. Consider the SOIC-8 package constraints if space is limited. Ensure thermal performance meets requirements given the 71mΩ switch resistance under load conditions.

Hot Swap Controllers Part Context

The ISL6151IB belongs to the ISL6185 USB power controller family manufactured by Intersil, now part of Renesas Electronics. This family consists of sixteen functional variants and three package options. The series is engineered for commercial and industrial temperature ranges, focusing on reliable power switching for USB interfaces. It represents a specialized solution for managing power delivery and fault protection in multi-port configurations.

Hot Swap Controllers Replacement Considerations

Consult Renesas Electronics Product Legacy Documents for officially confirmed substitute part numbers. Verify pin compatibility and electrical parameters before replacing with other members of the ISL6185 family. Do not assume cross-family compatibility without explicit manufacturer validation.
