TPS2557DRBR Typical application Circuitry Schematics

The TPS2557DRBR is a member of Texas Instruments' TPS255x and TPS255x-1 family, which are precision adjustable current-limited power distribution switches. These devices are designed for applications where precision current limiting is crucial, including scenarios that require robust load protection. Let's delve into a detailed circuit description of the TPS2557DRBR:

1. Input and Output Pins: - IN: This pin accepts the input voltage. In certain applications, this could be connected to a supply like a 5V source. - OUT: This pin delivers the current-limited voltage to the load.

2. Current Limit Setting: - ILIM: By attaching a resistor from this pin to ground, the desired current limit can be set. The current limit is inversely proportional to the resistor's value, meaning a smaller resistor will lead to a higher current limit and vice versa.

3. Enable and Control: - EN: This is the Enable pin. Applying a high voltage turns on the TPS2557DRBR, while a low voltage turns it off.

4. Fault Reporting: - FAULT: This open-drain output gets asserted (goes low) during over-current conditions or thermal shutdown events. It becomes high-impedance when the fault is resolved.

5. Automatic Retry or Latch-off: - The behavior after a fault differentiates TPS2557DRBR from some other models. TPS2557DRBR offers an auto-retry feature. In the event of a fault (like over-current), the device will automatically attempt to re-establish the connection once the fault condition has been cleared.

6. Status Reporting: - PG (Power Good): This open-drain output goes low if the output voltage falls below a specific threshold, indicating an issue with the power supply or a not "good" status.

7. Thermal Protection: - Built-in thermal shutdown functionality ensures that if the internal temperature exceeds a preset threshold, the TPS2557DRBR will shut off to prevent potential harm. Once the temperature decreases to an acceptable range, the device will auto-restart.

8. Ground: - GND: This serves as the ground reference for the TPS2557DRBR.

9. Other Pins: - D: Represents the drain of the internal N-channel MOSFET switch.

Depending on the specific package and its configuration, it might be internally tied to the OUT pin. - S: Refers to the source of the internal MOSFET. Depending on the configuration, this could be internally connected to the GND pin. General Considerations: - It's recommended to position decoupling capacitors close to the IN and OUT pins to ensure a stable operation. - Following best practices for PCB design is crucial. This encompasses proper grounding, trace widths, and the placement of components for optimal performance and reliability. For in-depth details, such as detailed application circuits, preferred component values, and specific design guidelines, always refer to the official TPS2557DRBR datasheet provided by Texas Instruments. This document will provide a comprehensive understanding of the device's features and design recommendations.
