Texas Instruments TPS2394DGKG4 is a single-channel hot-swap controller designed for robust operation in negative voltage systems. This device facilitates the safe insertion and removal of components from a live backplane operating at -48V nominal (rated for -80V to -36V). Key features include programmable current limiting, fault timeout, and slew rate control, enabling precise management of inrush current. The TPS2394DGKG4 incorporates UVLO (Under Voltage Lockout) protection and a latched fault mechanism for enhanced system reliability. Its 8-VSSOP package is suitable for surface-mount applications. This controller is commonly employed in telecommunications infrastructure and industrial power systems requiring reliable hot-swap functionality for negative voltage rails. The typical supply current is 700 µA, and it operates within a temperature range of -40°C to 85°C.
