UCC3919DTR TI Hot Swap Controller | 16-SOIC | 3V to 8V, 0.5A to 3A

Product Overview

The UCC3919DTR from Texas Instruments is a single-channel hot swap controller designed to manage inrush current and protect against overcurrent and short-circuit faults in power distribution systems. It operates over a supply voltage range of 3V to 8V and supports programmable current limits from 0.5A to 3A. The device integrates a 0.1Ω power MOSFET and provides fault reporting via a STATUS output. Housed in a 16-pin SOIC package, it is ideal for hot-swap and power-sequencing applications in telecom, networking, and industrial equipment.
