TPS259271DRCT TI eFuse | 10-VSON (3x3) | 5.5V, 5A, Adjustable Current Limit

Product Overview

The TPS259271DRCT from Texas Instruments is a compact, feature-rich eFuse power management IC designed for robust overcurrent and overvoltage protection. Housed in a 10-pin VSON package (3x3 mm), it integrates a low on-resistance (RON) N-channel MOSFET to minimize power loss. The device operates over a wide input voltage range of 2.7V to 5.5V and supports continuous load currents up to 5A. It offers adjustable current limit, fast overcurrent response, and thermal shutdown, making it ideal for protecting downstream circuitry in space-constrained applications.
