Overview
The TPS22954DSQR is a high-performance, single-channel load switch produced by Texas Instruments. This device is designed to operate over an input voltage range of 0.7 V to 5.7 V and can support a maximum continuous current of 5 A. It features a low on-resistance (RON) of 14 mΩ at VIN = 5 V, making it suitable for a variety of power distribution applications. The TPS22954DSQR is housed in a small, space-saving 10-pin WSON package with an integrated thermal pad, allowing for high power dissipation and efficient thermal management.
