TPS259481LYWPR TI eFuse | 12-DSBGA (2.43x1.74) | 4.5V-18V, 5A, 28mΩ

Product Overview

The TPS259481LYWPR is a high-performance eFuse power management IC from Texas Instruments, designed to provide robust protection and precise power distribution in space-constrained applications. Housed in a compact 12-DSBGA (2.43x1.74mm) package, this device integrates a low on-resistance (28mΩ typical) N-channel MOSFET to support continuous currents up to 5A. With an input voltage range of 4.5V to 18V, it is ideal for 5V, 9V, and 12V rails. The TPS259481LYWPR offers programmable overcurrent protection (OCP), overvoltage protection (OVP), undervoltage lockout (UVLO), and thermal shutdown, ensuring reliable operation in harsh environments. Its fast transient response and accurate current monitoring make it suitable for hot-swap, USB Type-C, and industrial applications.
