TPS22990DMLR

The TPS22990DMLR is a high-performance load switch from Texas Instruments, designed to provide efficient power management in various electronic applications. This device is particularly useful in systems where power efficiency and compact design are critical.

Key Features:

1. Load Switch Functionality: The TPS22990 is a single-channel load switch that allows for the control of power to a load. It can be used to turn on or off the power supply to a device, helping to manage power consumption effectively.

2. Low On-Resistance: The device features a low on-resistance (RDS(on)) of approximately 30 mΩ at 5V, which minimizes power loss and heat generation during operation. This characteristic is essential for battery-powered applications where efficiency is paramount.

3. Wide Input Voltage Range: The TPS22990 supports a wide input voltage range from 1.0V to 5.5V, making it suitable for various applications, including portable devices, consumer electronics, and industrial equipment.

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 TPS22990 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 low, the switch turns off, disconnecting the load from the power source.

6. Thermal Protection: The device is equipped with thermal shutdown protection, which helps prevent damage due to overheating. This feature is crucial in applications where the load switch may be subjected to high currents or environmental stress.

7. Compact Package: The TPS22990 is available in a small, space-saving package (such as a 2mm x 2mm VQFN), making it ideal for applications with limited board space.

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

   • Power management in portable devices
   • Battery-powered systems
   • Consumer electronics
