TPS259472ARPWR TI eFuse | 10-VQFN-HR (2x2) | 2.7V-23V, 5A

Product Overview

The TPS259472ARPWR 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 10-VQFN-HR (2x2) package, this device integrates a low on-resistance (RON) N-channel MOSFET to support continuous currents up to 5A. It operates over a wide input voltage range of 2.7V to 23V, making it suitable for a variety of systems requiring reliable overcurrent, overvoltage, and short-circuit protection. The TPS259472ARPWR features adjustable current limit, fast transient response, and thermal shutdown, ensuring safe operation under fault conditions. Its small footprint and advanced protection capabilities make it ideal for modern electronics where board space is at a premium.
