    The TPS2065DDBVR is a single-channel, current-limited power distribution switch manufactured by Texas Instruments. It is designed for applications requiring high-side power switching with current limiting and protection features.

    Key Features:

    • Current-Limited Power Switch: Provides protection against overcurrent conditions by limiting the output current.
    • Adjustable Current Limit: Allows for adjustable current limiting to match specific application needs.
    • Overtemperature Protection: Shuts down the switch if the junction temperature exceeds safe limits, protecting the device from damage.
    • Reverse Current Blocking: Prevents reverse current flow from the output to the input.
    • Operating Voltage Range: Supports an input voltage range of 2.7 V to 5.5 V, suitable for USB and other low-voltage applications.
    • Low On-Resistance: Features a low on-resistance of 70 mΩ (typical), ensuring minimal voltage drop and power loss.
    • Fault Reporting: Provides an active-low fault signal to indicate overcurrent, overtemperature, or other fault conditions.
    • Enable Control: Includes an enable pin for turning the switch on or off, allowing for power management and control.
    • Compact Package: Available in a small SOT-23-6 package, making it easy to integrate into space-constrained designs.

    Typical Applications:

    • USB Power Distribution: Ideal for USB ports and hubs, providing current limiting and protection for connected devices.
    • Consumer Electronics: Used in laptops, tablets, smartphones, and other portable devices for power management and protection.
    • Industrial Equipment: Provides reliable power switching and protection in industrial control systems and instrumentation.
    • Battery-Powered Devices: Extends battery life and protects sensitive components in battery-operated equipment.
    • Power Management Systems: Suitable for use in power management and distribution systems, ensuring safe and efficient operation.


    • Enhanced Protection: Offers robust protection features including current limiting, overtemperature protection, and reverse current blocking.
    • Adjustable Current Limit: Provides flexibility to set the current limit according to specific application requirements.
    • Compact and Efficient: Low on-resistance and small package size make it ideal for compact and efficient designs.
    • Easy Integration: Fault reporting and enable control facilitate easy integration into various power management and distribution applications.
