Product Overview: Texas Instruments TPS2064DGN

The Texas Instruments TPS2064DGN is a state-of-the-art, quad-channel USB power distribution switch, designed for applications requiring precision current limiting and power management. This compact and efficient device is housed in a 14-pin MSOP (DGN) package, making it an ideal choice for space-constrained applications. The TPS2064DGN is specifically engineered to provide up to 1.5A of continuous current across its four channels, catering to the needs of USB hubs and other peripherals requiring multiple USB power distribution paths.

Key Features

• Quad Independent Channels: The TPS2064DGN features four independent output channels, each capable of delivering up to 0.5A of continuous current, with the combined current of all channels not exceeding 1.5A.
• Accurate Current Limiting: Each channel is equipped with precise current-limiting circuitry, ensuring the protection of USB ports by preventing excessive current draw that could otherwise damage sensitive equipment.
• Thermal Overload Protection: The device includes built-in thermal overload protection that automatically shuts down the output if the die temperature exceeds safe operating limits, thereby safeguarding the device and connected peripherals from potential heat damage.
• Overcurrent Logic Output: An overcurrent logic output is available for each channel, providing a signal to the host system in the event of a current overload, which can be used for status reporting or fault diagnosis.
• Under-Voltage Lockout (UVLO): The TPS2064DGN incorporates an under-voltage lockout feature that ensures the switch remains off until the input voltage is stable and within its operating range.
• Low Standby Power: The device is optimized for low standby power consumption, making it suitable for battery-powered applications where power efficiency is critical.

Applications

The versatility of the TPS2064DGN allows it to be used in a wide array of applications. It is particularly well-suited for USB hubs, docking stations, and other computer peripherals. Additionally, it can be employed in various consumer electronics, networking equipment, and portable devices where multiple USB power distribution is required.

With its robust feature set and compact form factor, the Texas Instruments TPS2064DGN represents a reliable and efficient solution for managing power distribution in USB-based systems.
