The TPS2053BDR is an integrated circuit (IC) component that belongs to the family of power distribution switches manufactured by Texas Instruments. It is commonly used for USB port power management and current limiting in various electronic devices.
Key Features:
1. High-current power distribution: The TPS2053BDR supports up to 500 mA of continuous current and has a thermal shutdown protection feature that guards against excessive temperature rise.
2. USB port power management: With its USB compatibility, the IC selectively provides power to USB ports, enabling automatic current regulation. It allows the device to meet USB-IF specifications and provides a controlled, constant current to connected devices.
3. Adjustable current limit: The TPS2053BDR integrates a user-adjustable current limit feature, supporting different current ratings based on specific system requirements. This flexibility allows customization and compatibility with a wide range of USB-powered devices.
4. Fast overcurrent detection and response: The IC has a fast overcurrent detection and protection mechanism that shuts off the power supply to prevent damage to the device or connected peripherals. This feature enhances the safety and reliability of the overall system.
5. Undervoltage lockout (UVLO): The UVLO function integrated into the TPS2053BDR ensures that the device powers down when the input voltage falls below a certain threshold. This protection feature prevents erratic behavior and protects downstream components during power fluctuations or voltage fluctuations
