TPS2421-2DDAR TI Hot Swap Controller | 8-SO-POWERPAD | 3V-15V, 5A

Product Overview

The TPS2421-2DDAR from Texas Instruments is a versatile hot swap controller designed for applications requiring safe insertion and removal of circuit boards in live backplanes. It integrates a power MOSFET and current sense circuitry in a compact 8-SO-POWERPAD package, providing overcurrent protection, inrush current control, and reverse current blocking. Operating from 3V to 15V, it supports continuous load currents up to 5A, making it ideal for power distribution in telecom, industrial, and automotive systems.
