Product Overview: Texas Instruments TPS2081DR

The Texas Instruments TPS2081DR is a versatile and robust power distribution switch designed for applications that require multiple power switches in a single package. This integrated circuit is part of the TPS208x family and is optimized for managing power distribution in USB hubs and other applications where limited USB power needs to be distributed among various peripherals.

Key Features

• Multiple Power Switches: The TPS2081DR contains one 0.5A current-limited power switch, providing an efficient solution for power management and distribution.
• Enhanced Protection: The device includes built-in over-current protection to safeguard against excessive current draw, as well as thermal shutdown to prevent overheating. This ensures reliable operation and extends the life of both the switch and the connected peripherals.
• High Accuracy: The over-current limit is factory-trimmed to ensure precise control of the output current, offering a high level of protection for sensitive components.
• Low On-Resistance: The TPS2081DR features a low on-resistance of typically 105mΩ, which minimizes voltage drop and power loss, ensuring efficient power delivery to connected devices.
• Control and Status Flag: An active-low enable input allows the switch to be turned on or off as needed, while a status flag output provides a signal when the current limit or thermal shutdown is activated.

Applications

The TPS2081DR is ideal for a variety of applications, particularly in USB hubs and other systems where power distribution is critical. It can also be used in:

• Peripheral power management
• Hot-plug power supplies
• Portable electronics
• Self-powered and bus-powered USB systems

Package and Quality

The device is available in an 8-pin SOIC package, making it suitable for space-constrained applications. Texas Instruments ensures high-quality standards, and the TPS2081DR is no exception, providing reliable performance across a wide range of operating conditions.

With its combination of power management features, protection mechanisms, and compact form factor, the Texas Instruments TPS2081DR is an excellent choice for designers looking to enhance the power distribution capabilities of their systems.
