The TPS2069CDGNR-2 is a state-of-the-art USB power distribution switch from Texas Instruments, designed for applications where heavy capacitive loads and short circuits are likely to be encountered. This advanced device is tailored to provide up to 2.1A of continuous current with multiple operational features that ensure safety and efficiency in power management.

Key Features

• Current Limiting: The TPS2069CDGNR-2 is equipped with an accurate current-limiting feature that protects the USB port by preventing excessive current draw that can lead to overheating and damage.
• Thermal Shutdown: An integrated thermal shutdown mechanism enhances the safety of your system by automatically switching off the power if the internal temperature crosses a critical threshold.
• Reverse Voltage Protection: This device ensures that any reverse voltage applied to the output is blocked, thereby protecting your downstream circuitry from potential harm.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the switch remains off if the input voltage drops below a certain level, preventing erratic behavior of connected devices due to insufficient supply voltage.
