The TPS2047ADRG4 from Texas Instruments is a robust, high-performance power distribution switch designed for USB and other hot-swap applications. This device is part of the TPS204x family and is optimized for managing power distribution in systems where heavy capacitive loads and short circuits are likely to be encountered.

Key Features

• Multiple Power Distribution Switches: The TPS2047ADRG4 contains three individual power distribution switches, providing flexibility and support for multi-port applications.
• Current Limiting: Each switch features programmable current limiting to protect the host device from overcurrent conditions. This ensures reliable operation and extends the lifespan of both the switch and the host system.
• Thermal Shutdown Protection: With built-in thermal shutdown protection, the device automatically turns off the output if the die temperature exceeds a safe threshold, thereby preventing thermal damage.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the switch remains off when the input voltage falls below a certain threshold, preventing erratic behavior of the connected load during low voltage conditions.
• Fast Short-Circuit Response Time: The TPS2047ADRG4 is designed to respond quickly to short-circuit conditions, minimizing the potential for damage or system instability.

Applications

The TPS2047ADRG4 is suitable for a wide range of applications, including:

• USB hubs, docking stations, and peripherals
• Hot-swap power supplies
• Portable electronics
• Industrial and automotive systems

Technical Specifications

The device comes in a compact 16-pin SOIC (D) package, offering a space-saving solution for densely packed circuit boards. It operates over a wide input voltage range from 2.7 V to 5.5 V, making it versatile for various USB and battery-powered applications. The TPS2047ADRG4 also delivers continuous output current up to 500 mA per channel, with the ability to handle higher transient loads.
