Overview
The TPS2330IDRG4, produced by Texas Instruments, is a single-channel hot-swap power controller designed for use in various power management applications. This device utilizes an external N-channel MOSFET as a high-side switch, providing features such as overcurrent protection, inrush current control, and power-good reporting. The TPS2330IDRG4 is part of the TPS2330 and TPS2331 family, differing primarily in the enable pin configuration, with the TPS2330 having an active-low enable and the TPS2331 having an active-high enable.
