TPS22953DSQR

Power Distribution Switches, Load Drivers Overview

The TPS22953DSQR is a single-channel N-channel power distribution switch manufactured by Texas Instruments. It operates within a load voltage range of 2.5V to 5.7V and supports a maximum output current of 5A. The device features a typical on-resistance (RON) of 14 milliohms, ensuring efficient power delivery. Key timing parameters include a maximum run time of 1.265 milliseconds and a maximum idle time of 6 microseconds. The component is housed in a 10-WSON package with dimensions of 2x2 mm, designed for surface-mount installation. It functions as a high-side switch with non-inverted input control.
