TPS25221DRVT TI Power Switch | 6-WSON (2x2) | 2.5-5.5V, 2.1A, 73mΩ

Product Overview

The TPS25221DRVT from Texas Instruments is a precision adjustable current-limited power switch designed for applications requiring up to 2.1A of continuous current. Housed in a compact 6-pin WSON (2x2 mm) package, this device integrates a low on-resistance N-channel MOSFET (typical 73 mΩ) to minimize power loss and heat dissipation. It operates over a wide input voltage range of 2.5V to 5.5V, making it suitable for both 3.3V and 5V power rails. The TPS25221DRVT features an adjustable current limit set by an external resistor, with accuracy better than ±10% at 1A. Additional protection includes thermal shutdown, reverse current blocking, and under-voltage lockout (UVLO). The device is ideal for USB ports, hot-swap applications, and general-purpose power distribution in industrial, automotive, and consumer electronics.
