TPS259814LRPWR TI eFuse | 10-VQFN-HR (2x2) | 5.5V, 5A, 28mΩ

Product Overview

The TPS259814LRPWR is a high-performance eFuse (electronic fuse) from Texas Instruments, designed to provide robust overcurrent and overvoltage protection for power distribution systems. Housed in a compact 10-VQFN-HR (2x2 mm) package, this device integrates a low on-resistance (28 mΩ) N-channel MOSFET to minimize power loss and heat dissipation. It supports an input voltage range of 2.7V to 5.5V and can handle continuous currents up to 5A. The TPS259814LRPWR features programmable current limit, fast overcurrent response, and thermal shutdown, making it ideal for protecting sensitive loads in space-constrained applications.
