TPS259461ARPWR TI eFuse | 10-VQFN-HR (2x2) | 4.5V-18V, 5A, 28mΩ

Product Overview

The TPS259461ARPWR is a high-performance eFuse power management IC from Texas Instruments, designed for robust circuit protection in compact applications. Housed in a 10-pin VQFN-HR (2x2 mm) package, it integrates a low on-resistance (28 mΩ) N-channel MOSFET to provide overcurrent, overvoltage, and short-circuit protection. With an input voltage range of 4.5 V to 18 V and a continuous current rating of 5 A, it is ideal for hot-swap, USB Type-C, and industrial applications. The device features programmable current limit, fast transient response, and thermal shutdown, ensuring reliable operation in harsh environments.
