The TPS2033D from Texas Instruments is a robust, single-channel USB power distribution switch designed for applications where heavy capacitive loads and short-circuits are likely to be encountered. This device is particularly well-suited for USB applications by providing up to 500 mA as required by the USB 2.0 specification.

Key Features

• Current Limiting: The TPS2033D offers built-in current limiting to protect the host device from potentially damaging overcurrent conditions.
• Thermal Shutdown: With an integrated thermal shutdown feature, the device ensures protection against overheating, enhancing system safety and reliability.
• Fast Transient Response: The device is capable of handling fast transients on the bus line, ensuring stable operation under fluctuating power demands.
• Low On-Resistance: The switch features a low on-resistance of typically 70 mΩ, minimizing voltage drop and power loss.
• Under-Voltage Lockout (UVLO): The TPS2033D includes UVLO to ensure that the switch remains off when the input voltage is too low, preventing malfunction.
• Fault Reporting: A fault output flag is available to indicate overcurrent, undervoltage, or thermal shutdown conditions to the system controller.

Applications

The versatility of the TPS2033D makes it ideal for a wide range of applications, including:

• USB hubs, peripherals, and monitors
• Hot-swap supplies
• Portable consumer electronics
• Self-powered and bus-powered USB systems

Package and Availability

The TPS2033D is available in an 8-pin SOIC (D) package, offering a compact footprint for space-constrained applications. It is designed to operate over a temperature range of -40°C to 85°C, accommodating a broad spectrum of environmental conditions. Texas Instruments provides comprehensive technical support, including datasheets, reference designs, and application notes to facilitate the integration of the TPS2033D into your design.
