ISL61851ICBZ-T

Hot Swap Controllers Overview

The ISL61851ICBZ-T is a dual-channel hot-swap voltage controller designed for USB port power management. It integrates two P-channel MOSFET switches with an on-resistance of 71 milliohms each, enabling independent overcurrent protection for multiple ports. The device operates within a supply voltage range of 2.3V to 5.5V and supports commercial temperature operation from 0°C to +70°C. Packaged in an 8-lead SOIC (SOIC-8) format, it features internal current monitoring and fault management capabilities including thermal limiting and UVLO.

Hot Swap Controllers Feature Summary
