TPS22968DPUR

The TPS22968DPUR is a high-performance load switch from Texas Instruments, designed to provide efficient power management in various electronic applications. This device is particularly useful for controlling power to different components in a system, such as microcontrollers, sensors, and other peripherals.

Key Features:

1. Load Switch Functionality: The TPS22968DPUR is a single-channel load switch that allows for the control of power to a load. It can turn on or off the power supply to a device, enabling efficient power management.

2. Low On-Resistance: The device features a low on-resistance (RDS(on)), typically around 30 mΩ, which minimizes power loss and heat generation during operation. This characteristic is crucial for battery-powered applications where efficiency is paramount.

3. Wide Input Voltage Range: The TPS22968DPUR supports a wide input voltage range, typically from 1.0 V to 5.5 V, making it suitable for various applications, including portable devices and battery-operated systems.

4. Controlled Rise and Fall Times: The device includes built-in controlled rise and fall times, which help to reduce inrush current and prevent voltage spikes that could damage sensitive components.

5. Enable Functionality: The TPS22968DPUR features an enable pin that allows for easy control of the load switch. When the enable pin is high, the switch is on, allowing current to flow to the load. When the enable pin is low, the switch turns off, disconnecting the load from the power supply.

6. Thermal Protection: The device is designed with thermal protection features to prevent overheating, ensuring reliable operation even under high load conditions.

7. Compact Package: The TPS22968DPUR is available in a small, space-saving package (typically a 2 mm x 2 mm VQFN), making it ideal for applications where board space is limited.

8. Applications: This load switch is suitable for a variety of applications, including:

   • Power management in portable devices
   • Battery-powered systems
   • Power sequencing
   • Hot-swap applications
   • General-purpose load switching
