The TPS2065DR from Texas Instruments is a versatile and robust integrated circuit designed to provide power distribution controls for USB ports. As part of the Texas Instruments power management product line, this device is specifically engineered to handle up to 1A of continuous load current with multiple devices on a single port.

Key Features

• Current Limiting: The TPS2065DR offers built-in current limiting to protect the host device from over-current conditions. This ensures safe operation even when downstream devices draw excessive current.
• Thermal Shutdown: With an intelligent thermal shutdown feature, the switch prevents overheating by automatically turning off when the junction temperature exceeds safe limits.
• Under-Voltage Lockout (UVLO): This safety feature ensures that the switch remains off when the input voltage falls below a certain threshold, preventing erratic operation of connected devices.
• Fast Transient Response: The device is designed to respond quickly to transient loads, thereby providing stable power supply to connected USB devices.
• Reverse Voltage Protection: The TPS2065DR is equipped with reverse voltage protection to safeguard against potential damage caused by incorrect power supply connections.

Applications

The TPS2065DR is ideal for a variety of USB power distribution applications, including:

• USB Hubs
• Desktop and Notebook Computers
• Peripheral Power Management
• Portable Equipment
