TPS22917DBVT

Power Distribution Switches, Load Drivers Overview

The TPS22917DBVT is a single-channel load switch from Texas Instruments designed for power distribution applications. It operates within an input voltage range of 1 V to 5.5 V and supports a maximum continuous output current of 2 A. The device features a low on-resistance, typically 80 mΩ at 5 V input, ensuring minimal power loss. It includes adjustable rise time via an external capacitor to manage inrush current and offers configurable output discharge through the QOD pin. The component exhibits ultra-low quiescent current of 0.5 µA in the on-state and 10 nA in the off-state. It incorporates a true reverse current blocking (RCB) feature and an intelligent pull-down resistor on the ON pin to prevent floating states during power-up.
