TPS22976NDPUT

The TPS22976NDPUT 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 battery-powered systems, portable devices, and other applications where power efficiency is critical.

Key Features:

1. Load Switch Functionality: The TPS22976 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, helping to manage power consumption effectively.

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 maintaining efficiency in battery-operated devices.

3. Wide Input Voltage Range: The TPS22976 supports a wide input voltage range, typically from 1.0 V to 5.5 V, making it suitable for various applications, including those powered by lithium-ion batteries and other low-voltage sources.

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 in the circuit.

5. Enable Functionality: The TPS22976 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 source.

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 TPS22976NDPUT 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 routing in consumer electronics
   • USB power delivery systems
   • Automotive applications

Electrical Characteristics:

• Input Voltage Range: 1.0 V to 5.5 V
