The TPS22948DCKR is a compact, low-voltage, single-channel load switch produced by Texas Instruments. This advanced switch is designed to operate with an input voltage range of 1.62V to 5.5V, making it an ideal choice for battery-powered and portable applications. Its ultra-small 6-pin SC-70 package makes it perfect for space-constrained applications.
Key Features
- Input Voltage Range: The device supports a wide input voltage range from 1.62V to 5.5V, accommodating a variety of power sources.
- Low On-Resistance: The TPS22948DCKR features a low on-resistance (RON) that typically stands at 105 mΩ at 5V, ensuring efficient power delivery and minimal voltage drop across the switch.
- Current Limit: To protect the power source and load, the device incorporates a current limit feature which is factory set at 150 mA.
- Quick Output Discharge: An integrated quick output discharge transistor provides a fast discharge of the load capacitance when the switch is turned off, preventing unwanted power residue in the system.
- Controlled Slew Rate: The TPS22948DCKR is engineered with a controlled slew rate to minimize inrush current, which helps in reducing the noise and voltage spikes on the power lines.
- Low Quiescent Current: It boasts a low quiescent current of 20 nA (typical) when the switch is off, contributing to power conservation in battery-powered applications.
- Under-Voltage Lockout (UVLO): The UVLO feature ensures that the switch remains off when the input voltage falls below a certain threshold, preventing erratic operation of the load.
Applications
The TPS22948DCKR is versatile and can be used in a multitude of applications, including but not limited to:
- Smartphones and Tablets
- Wireless Headsets and Wearables
- Portable Medical Devices
- Power Management for Peripheral Ports
