MAX5954LETX+T

Hot Swap Controllers Overview

The MAX5954LETX+T is a hot plug controller designed for PCI Express applications. It features three independent channels with integrated power switches, operating within a supply voltage range of 3V to 3.6V and 10.8V to 13.2V. The device supports programmable current limiting and fault timeout settings. It includes protection mechanisms such as overvoltage protection (OVP), undervoltage lockout (UVLO), thermal limiting, and latched fault states. Packaged in a 36-TQFN (6x6) surface-mount enclosure, it operates across an extended temperature range of -40°C to +85°C.
