TPS22917DBVR Power Switch/Driver 1:1 P-Channel 2A SOT-23-6
The TPS22917DBVR is a high-performance P-channel MOSFET load switch designed by Texas Instruments (TI) for low-voltage power management applications. Built on an ultra-low-leakage architecture, it operates with a supply voltage range of 1V to 5.5V and supports a maximum continuous output current of 2A, making it ideal for battery-powered devices, USB interfaces, and hot-swap systems. The device features a single-channel, 1:1 input-to-output configuration with a typical on-resistance of 80mΩ, minimizing power loss and voltage drop during operation. Its SOT-23-6 surface-mount package (3.05mm x 1.75mm) ensures compact integration while meeting RoHS compliance for environmentally friendly designs.
Key Features & Functional Advantages
The TPS22917DBVR integrates advanced protection mechanisms, including reverse-current blocking to prevent unintended battery discharge and load release functionality that disconnects outputs during shutdown to avoid back-powering. Its controlled slew rate reduces inrush current, protecting sensitive downstream components during hot-plugging. The device operates across a wide temperature range (-40°C to +125°C), ensuring reliability in harsh industrial or automotive environments. Additionally, its non-inverting enable input simplifies control logic integration, while the high-side output configuration enables direct connection to system loads without external level shifters.
Applications
This load switch is widely deployed in portable electronics such as smartphones, tablets, and wearables, where it manages power sequencing for peripherals like cameras, sensors, and displays. In USB Type-C and Power Delivery (PD) systems, it provides voltage regulation and overcurrent protection for connected devices. The TPS22917DBVR also excels in industrial automation, where it controls actuators, solenoids, and LED drivers with precise on/off switching. Its low quiescent current (<1μA) makes it suitable for energy harvesting applications, extending battery life in IoT nodes and wireless sensors.
