Pinout
The TPS22934YZVR is a load switch from Texas Instruments designed for power management applications. It comes in a 4-ball, 0.4-mm pitch DSBGA (Die-sized Ball Grid Array) package, meaning it has 4 pins or balls.
Here is a concise explanation of its pin functions:
1. VIN: This is the input voltage pin where the supply voltage is connected. It takes the voltage from the power source that needs to be controlled by the switch.
2. VOUT: This is the output voltage pin. It delivers the regulated output to the load once the switch is turned on.
3. ON: This pin is used to control the state of the switch. When a high signal is applied, the switch turns on, allowing current to pass from VIN to VOUT.
4. GND: This is the ground pin, which provides the reference point for the input and output voltages.
The TPS22934 is designed to provide controlled power delivery with features like fast turn-on time and low ON-resistance, making it suitable for battery-powered applications.
