UCC3921DTR TI Hot Swap Controller | 8-SOIC | 2.7V-13V, 1.5A

Product Overview

The UCC3921DTR from Texas Instruments is a single-channel hot swap controller designed for 2.7V to 13V supply rails. It allows safe insertion and removal of boards in live backplanes, with programmable current limit up to 1.5A. The device integrates a 30mΩ power MOSFET and provides fault protection including overcurrent, short-circuit, and thermal shutdown. Housed in an 8-pin SOIC package, it is ideal for space-constrained applications requiring robust power management.
