TPS2051CDBVR/TPS2051CDBVT - Texas Instruments Single Channel USB Power Distribution Switch

The TPS2051CDBVR and TPS2051CDBVT are single channel, current-limited, power distribution switches designed by Texas Instruments, optimized for USB applications. They are part of a family of USB power distribution switches that protect USB ports against overcurrent and short-circuit conditions, ensuring the safety and reliability of the system they are integrated into.

These devices are housed in small, 6-pin SOT-23 (DBV) and 6-pin SOT-23 (DBT) packages, making them ideal for space-constrained applications. The TPS2051C series is capable of delivering up to 1.5A of continuous current, which is suitable for higher-power USB peripherals, and supports the USB 2.0 standard.

Key features of the TPS2051CDBVR/TPS2051CDBVT include:

• Current-Limiting Protection: The switches offer built-in current limiting to protect the host device from overcurrent conditions. This is crucial for preventing damage to USB ports and connected devices.
• Thermal Shutdown: An integrated thermal shutdown feature ensures that the switch turns off in the event of excessive heat, providing an additional layer of protection.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the switch remains off if the input voltage falls below a certain threshold, preventing malfunction at low voltages.
• Fast Transient Response: The device is designed to respond quickly to transient loads, maintaining stable operation for the connected USB device.
• Controlled Rise Time: The TPS2051C series features a controlled output rise time to reduce inrush current, which is beneficial for sensitive downstream circuits.
• Reverse Current Protection: These switches prevent reverse current flow from the output to the input when the switch is powered off, safeguarding the upstream power source.

The TPS2051CDBVR/TPS2051CDBVT are versatile power switches that can be used in a variety of USB-powered devices such as hubs, monitors, docking stations, and more. Their robust protection features ensure that USB ports and peripheral devices are shielded from electrical stress, while their small footprint makes them suitable for portable and compact electronic designs.

With the reliability and quality of Texas Instruments, these power distribution switches are an excellent choice for designers looking to enhance the safety and durability of their USB interfaces.
