Product Overview: Texas Instruments TPS2085DR

The TPS2085DR is a high-quality power distribution switch from Texas Instruments, designed for applications that require multiple power switches in a single package. This integrated circuit is part of the TPS208x family and is specifically engineered to enhance the functionality of USB and other hot-swap applications.

Constructed with a 2.7-V to 5.5-V operating range, the TPS2085DR is optimized for universal serial bus (USB) and other systems powered from a 3.3-V or 5-V bus. It is a quintessential component for designers looking to simplify the power management in systems with multiple USB ports or other peripherals requiring power switching capabilities.

Key Features

• Multiple Power Switches: The TPS2085DR incorporates four independent 0.5-A switches, allowing for individual control of each connected device.
• Over-Current Protection: Each switch has built-in over-current and short-circuit protection, ensuring the safe operation of connected devices and the power bus.
• Thermal Shutdown: An integrated thermal shutdown feature protects the device and the system from excessive temperature rise.
• Under-Voltage Lockout (UVLO): This feature ensures that the switches remain off until the supply voltage reaches a safe operating level.
• Low On-Resistance: The low on-resistance (R_ON) of the switches minimizes voltage drop and power dissipation, making the TPS2085DR an efficient choice for power distribution.

Applications

The TPS2085DR is ideal for a variety of applications, including:

• USB hubs and peripherals
• Hot-swap power management
• Portable consumer electronics
• Power distribution for multiple peripheral devices
