Introduction
This User’s Guide describes the use and features of the simple −48-V hot swap evaluation
module (EVM). This EVM can be used to learn about the TPS2398 and TPS2399 hot swap
controller integrated circuits (ICs) from Texas Instruments (TI). The TPS2398 and TPS2399 are
negative voltage hot swap controllers intended for use in systems needing to hot swap telecom
distribution-level voltages. They integrate inrush current control, peak current limiting, electronic
circuit breaker, enable input, and current fault indication. The EVM is a PCB-based tool featuring
either device, and can be used to evaluate device operation in simulated live insertion events.
