Features

The TPS22917DBVR is a small, low-power load switch from Texas Instruments designed for space-constrained applications. It features an input voltage range of 1 V to 5.5 V, supporting a wide variety of power rails. The switch has an ultra-low on-resistance (RON) of 60 mΩ, ensuring minimal voltage drop and power loss across the device.
This load switch includes an adjustable slew rate control to manage inrush current, protecting downstream components during power-up. It offers an active-high ON control and a quick output discharge (QOD) function, which ensures the output is rapidly discharged to ground when the switch is turned off.
The TPS22917DBVR supports a maximum continuous current of 2 A, making it suitable for high-current loads. It is housed in a compact SOT-23-6 package, ideal for applications requiring high-density board layouts. Furthermore, it features built-in over-current protection and thermal shutdown, enhancing system reliability.
Overall, the TPS22917DBVR is suitable for consumer electronics, portable devices, and other applications where efficient power management and space-saving design are crucial.

Package

The TPS22917DBVR is a load switch from Texas Instruments, provided in a small SOT-23-6 package. This package type is compact, making it suitable for space-constrained applications.

Pinout

The TPS22917DBVR is a load switch IC produced by Texas Instruments. It comes in a 5-pin SOT-23 package. The pin functions are as follows:
1. VIN: This is the input voltage pin where the supply voltage is applied. It connects to the power source.
2. VOUT: This is the output voltage pin where the load is connected. It delivers the regulated power from the VIN pin to the load.
3. ON: This is the control pin used to enable or disable the load switch. A high signal on this pin activates the switch, while a low signal turns it off.
4. GND: This is the ground pin and completes the circuit by connecting to the negative terminal of the power supply.
5. NC (No Connect): This pin is not internally connected and is typically left floating or grounded as needed by the design.
The TPS22917 is designed for efficient power management, supporting applications where power sequencing and controlled load switching are needed.
