TPS259481AYWPR TI eFuse | 12-DSBGA (2.43x1.74) | 4.5V-18V, 5A, 28mΩ

Product Overview

The TPS259481AYWPR is a high-performance eFuse or power switch from Texas Instruments, designed to provide robust protection for power distribution systems. It integrates a low on-resistance (28mΩ) N-channel MOSFET to support continuous currents up to 5A over an input voltage range of 4.5V to 18V. The device is housed in a compact 12-DSBGA package (2.43mm x 1.74mm), making it ideal for space-constrained applications. It offers programmable overcurrent protection, output slew rate control, and thermal shutdown, ensuring safe operation under fault conditions.
