The TPS2041P is a robust, single-channel, current-limited, power-distribution switch designed by Texas Instruments for applications requiring power distribution and management in digital systems. This integrated circuit (IC) is tailored to meet the needs of USB and other hot-swap applications.

Key Features

• Current Limiting: The TPS2041P offers an adjustable current limit, which can protect the device and the system from damage due to overcurrent conditions.
• Thermal Shutdown: With built-in thermal shutdown protection, the device automatically turns off if it overheats, thus safeguarding the system's integrity.
• Under-Voltage Lockout (UVLO): This feature ensures that the switch remains off if the input voltage is too low, preventing erratic operation.
• Fast Transient Response: The device is capable of handling fast transients, which is essential for maintaining stability and performance in rapidly changing load conditions.
• Controlled Rise Time: The TPS2041P has a controlled output rise time which reduces inrush current and minimizes the risk of system voltage droop when the switch is enabled.

Applications

The TPS2041P is versatile and can be used in a variety of applications, including:

• USB hubs, peripherals, and powered ports
• Hot-swap power supplies
• Portable devices with plug-in power modules

Technical Specifications

• Input Voltage Range: 2.7V to 5.5V, making it suitable for low-power and USB-powered applications.
• Output Current: Up to 0.5A continuous current with current limiting to manage power distribution.
• Package: Available in an 8-pin PDIP (Plastic Dual-In-Line Package), which is easy to handle and integrate into various designs.
• Operating Temperature: Designed to function reliably over an industrial temperature range of -40°C to 85°C.
