TPS2554DRCR

The TPS2554DRCR is a power management integrated circuit (IC) produced by Texas Instruments. It is designed primarily for USB power distribution applications, providing a robust solution for controlling power delivery in various electronic devices. Below is a detailed description of its key features and specifications:

General Overview:

• Type: Power Distribution Switch
• Package: The TPS2554DRCR comes in a compact 10-pin VQFN (Very Thin Quad Flat No-lead) package, which allows for efficient thermal management and space-saving on printed circuit boards (PCBs).

Key Features:

1. Current Limit: The TPS2554 offers adjustable current limiting, which can be set using external resistors. This feature helps protect both the power source and the load from overcurrent conditions, making it suitable for applications where power management is critical.

2. Power Path Management: The device supports seamless power path management, allowing it to switch between different power sources without interruption. This is particularly useful in battery-powered devices that may need to switch between battery and external power.

3. Reverse Current Protection: The TPS2554 includes built-in reverse current protection, preventing current from flowing back into the power source when the load is disconnected or when the device is powered off.

4. Thermal Protection: The IC is equipped with thermal shutdown capabilities, which protect the device from overheating by shutting down the output if the junction temperature exceeds a certain threshold.

5. Low On-Resistance: The device features a low on-resistance (RDS(on)), which minimizes power loss and heat generation during operation, enhancing overall efficiency.

6. Wide Input Voltage Range: The TPS2554 can operate over a wide input voltage range, typically from 2.7V to 5.5V, making it versatile for various applications, including USB power delivery.

7. Enable Function: The device includes an enable pin that allows for easy control of the power switch, enabling or disabling the output as needed.

8. Status Indicator: The TPS2554 provides a status output that indicates whether the device is in a fault condition, such as overcurrent or thermal shutdown, allowing for easy monitoring and diagnostics.

Applications:

The TPS2554DRCR is suitable for a variety of applications, including:

• USB power distribution in smartphones, tablets, and other portable devices.
