9 Detailed Description

9.1 Overview

The TPS2477x Hot Swap features a programmable current limit, power limit, and fast trip threshold. It also has

dual timers: one for inrush and one during over current faults. Finally it features an analog current monitor that

can be used to provide current information to a microcontroller.
