TPS2087DR Power Distribution Switch by Texas Instruments
The TPS2087DR from Texas Instruments is a high-quality power distribution switch designed for applications where multiple USB ports require individual power switching and current limiting capabilities. This integrated circuit is part of TI's power management product line and is specifically tailored to enhance the functionality and safety of bus-powered peripheral devices.
The TPS2087DR comes in an 8-pin SOIC (Small Outline Integrated Circuit) package, providing a compact solution for space-constrained applications. Its design is optimized for dual-channel distribution, making it an ideal choice for managing power in dual USB ports with a single chip.
Key Features:
- Dual Independent Channels: Each channel can independently control and protect each USB port, ensuring reliable operation.
- Current-Limiting Protection: The device provides built-in current limiting to prevent damage from overcurrent conditions, enhancing the safety of connected devices.
- Thermal Shutdown: An integrated thermal shutdown feature protects the switch and the USB ports from overheating, further ensuring the longevity of the product.
- Under-Voltage Lockout (UVLO): This feature ensures that the switch remains off when the input voltage is too low, thus protecting the device and peripherals.
- Fast Overcurrent Response: The TPS2087DR reacts quickly to overcurrent events, minimizing the risk of damage to the USB ports and connected devices.
- Low On-Resistance: The low on-resistance of the internal FET reduces power loss and improves efficiency.
Applications:
- USB Hubs
- Peripheral Power Management
- Desktop and Notebook Computers
- Consumer Electronics
- Docking Stations
The TPS2087DR is not only a robust solution for power distribution but also contributes to the overall system stability and integrity. Its small form factor and dual-channel operation make it a versatile component for a wide range of USB power management applications. The inclusion of several protective features ensures that the TPS2087DR can safeguard both the power source and the devices connected to it, making it a reliable choice for designers and engineers looking to enhance their power distribution systems.
