Hot Swap Controllers datasheet and documents for ISL61851DCBZ

ISL61851DCBZ

Hot Swap Controllers Overview

The ISL61851DCBZ is a dual-channel hot swap voltage controller designed for USB port power management. It operates within a supply voltage range of 2.3V to 5.5V and supports an output current of up to 600mA per channel. The device features an internal high-side switch and integrates comprehensive protection mechanisms, including overcurrent fault timeout, latch-up fault response, thermal limiting, and undervoltage lockout (UVLO). It is housed in an 8-SOIC package with a width of 3.90mm and functions reliably across a commercial temperature range of 0°C to +70°C.

Hot Swap Controllers Feature Summary
