The TPS2010AD from Texas Instruments is a sophisticated USB power distribution switch designed to enhance the safety and efficiency of USB power management. This device is part of the TPS201xA family of current-limited, power-distribution switches optimized for self-powered and bus-powered Universal Serial Bus (USB) applications.
Key Features
- Current Limiting: The TPS2010AD incorporates precise current-limiting capabilities to protect the USB port from overcurrent conditions which are common in faulty USB peripherals or during hot-plug events.
- Fast Overcurrent Response: The device responds to overcurrent conditions in a swift manner, typically within 1 µs, ensuring quick protection for the host device.
- Thermal Shutdown: Integrated thermal shutdown protection ensures that the switch remains off until the device has cooled to a safe operating temperature.
- Under-Voltage Lockout (UVLO): The UVLO feature ensures that the switch remains off if the input voltage falls below a minimum threshold, thus protecting both the switch and the downstream devices.
- Controlled Rise Time: The switch limits the inrush current during enabling, providing a controlled rise time and reducing the likelihood of voltage droop on the power bus.
- Open-Drain Fault Flag: An open-drain fault flag output provides a signal to the host controller when an overcurrent, thermal shutdown, or UVLO event occurs.
Applications
The TPS2010AD is ideal for a wide range of applications, including:
- USB Hubs
- Desktop and Notebook PCs
- Peripheral Power Management
- Hot-Plug Power Supplies
Technical Specifications
- Input Voltage Range: 2.7 V to 5.5 V
