TPS25984B0RZJR

Overview

The TPS25984B0RZJR is a high-current electronic fuse manufactured by Texas Instruments, designed for robust power distribution and circuit protection. It features an integrated N-channel MOSFET capable of handling up to 30A continuous load current with a maximum input voltage range of 2.7V to 26V. The device incorporates precise current limiting with ±1.5% accuracy and supports hot-swap operations. Key protection mechanisms include overvoltage protection (OVP), undervoltage lockout (UVLO), and thermal shutdown. Packaged in a compact 24-VQFN (4x4mm) footprint with exposed pad, it ensures efficient heat dissipation and reliable performance across industrial temperature ranges.
