TPS259851RQPR TI eFuse | 26-VQFN-HR(5x4.5) | 5.5V-18V, 5A

Product Overview

The TPS259851RQPR is a high-performance eFuse power management IC from Texas Instruments, designed to provide robust protection and precise power distribution in modern electronic systems. Housed in a compact 26-pin VQFN-HR package (5mm x 4.5mm), this device integrates a low on-resistance power MOSFET (typical 28mΩ) with advanced protection features including overcurrent, overvoltage, undervoltage, reverse current blocking, and thermal shutdown. It operates over a wide input voltage range of 5.5V to 18V and supports continuous load currents up to 5A. The TPS259851RQPR is ideal for hot-swap, power distribution, and fault isolation applications in industrial, telecom, and automotive systems.
