TPS259474ARPWR TI eFuse | 10-VQFN-HR (2x2) | 4A, 2.7V-18V

Product Overview

The TPS259474ARPWR is a high-performance eFuse from Texas Instruments, designed to provide robust protection for power distribution systems. It integrates a low on-resistance MOSFET (typical 28mΩ) to minimize power loss and supports a wide input voltage range from 2.7V to 18V. The device offers adjustable current limit up to 4A, overvoltage protection, undervoltage lockout, and thermal shutdown. Housed in a compact 10-VQFN-HR (2x2 mm) package, it is ideal for space-constrained applications requiring reliable circuit protection.
