TPS259850RQPR TI eFuse | 26-VQFN-HR (5x4.5) | 5.5V, 8A, 28mΩ

Product Overview

The TPS259850RQPR from Texas Instruments is a high-performance eFuse (electronic fuse) designed for power management and protection in a wide range of applications. It integrates a low on-resistance (28mΩ) N-channel MOSFET with a comprehensive set of protection features, including overcurrent, overvoltage, undervoltage, reverse current, and thermal shutdown. The device operates from an input voltage range of 2.7V to 5.5V and supports continuous currents up to 8A. Packaged in a compact 26-VQFN-HR (5x4.5mm) package, it is ideal for space-constrained designs requiring robust power path protection.
