ISL61851JCBZ-T

Hot Swap Controllers Overview

The ISL61851JCBZ-T is a dual-channel hot-swap voltage controller designed for USB port power management. It integrates two P-channel MOSFET switches with internal current monitoring and fault protection. The device operates within a supply voltage range of 2.3V to 5.5V and supports an output current up to 1.5A per channel. It features automatic retry, fault timeout, thermal limiting, undervoltage lockout (UVLO), and on-resistance control. The component is housed in an 8-SOIC package and is rated for commercial operating temperatures from 0°C to +70°C.

Hot Swap Controllers Feature Summary

• Dual independent channels with integrated P-channel MOSFETs for precise overcurrent protection
• Automatic retry mechanism and configurable fault timeout for robust system recovery
• Thermal limiting and undervoltage lockout (UVLO) ensure safe operation under varying conditions

Hot Swap Controllers Applications

• USB hub power distribution
• Peripheral device hot-swapping
• Multi-port power management systems

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging versus tube variants. Confirm RoHS compliance status as documentation may vary by production batch. Check for End-of-Life notifications or Product Change Notices affecting availability. Ensure the supplier provides valid traceability documents for the Renesas/Intersil origin.

Hot Swap Controllers Selection Notes

Select this variant when dual-channel USB protection is required with integrated switching capabilities. Compare against other ISL61851 family members for differences in current ratings, package types, or temperature ranges. Verify that the 8-SOIC footprint matches the target PCB layout constraints. Ensure the 1.5A per-channel rating meets the load requirements without exceeding thermal limits.
