TPS22945DCKR TI Load Switch | SC-70-5 | 5.5V, 2A, 60mΩ

Product Overview

The TPS22945DCKR from Texas Instruments is a small, low-RON load switch with controlled turn-on. It supports a maximum input voltage of 5.5V and a continuous current of 2A. The device features a low on-resistance of 60mΩ (typical) to minimize power loss and voltage drop. It is available in a compact SC-70-5 package, making it ideal for space-constrained applications. The TPS22945 includes an active high enable input and an internal pull-down resistor to ensure the switch is off when enable is not driven.
