LM5050MK-1/NOPB Typical application Circuitry

LM5050MK-1/NOPB

The LM5050MK-1/NOPB is part of a series of high-side OR-ing FET controllers from Texas Instruments, specifically designed for managing power rails with multiple sources, such as in redundant power supply systems. It controls an external N-channel MOSFET to provide a low loss replacement to power diodes.

1. Pin Configuration:

- VIN (Voltage Input Pin): Connect this pin to the power source that needs to be OR-ed. A broad range of input voltages can be used to operate the LM5050MK-1/NOPB.

- VOUT (Voltage Output Pin): This pin connects to the load and is also the system voltage rail that is being OR-ed with another power source.

- GATE (Gate Drive Output Pin): attaches to the external N-channel MOSFET's gate. It drives the gate to turn on or off the MOSFET based on the voltage differences.

- GND (Ground Pin): This should be connected to the system ground.

2. Circuit Connection:

- OR-ing Function: For the OR-ing function, connect the source of the N-channel MOSFET to the VIN pin of the LM5050MK-1/NOPB, and the drain to the system power rail (VOUT).

- Control Features: The LM5050MK-1/NOPB provides a charge pump to fully enhance the N-channel MOSFET, ensuring low on-resistance and minimal voltage drop.

- Status Flag: An open-drain power good flag (PG) is provided, which indicates when the external MOSFET is off and the input voltage is below the output voltage.

- UVLO (Under Voltage Lock Out): The UVLO feature prevents the MOSFET from turning on when the input voltage is below a certain threshold, ensuring reliable operation.

3. Protection Mechanisms:

- The LM5050MK-1/NOPB is equipped with a cross-conduction prevention logic that avoids simultaneous conduction of both high-side and low-side MOSFETs in a synchronous rectifier application.

- It also features a thermal shutdown to protect the device under extreme conditions.

4. Efficiency Considerations:

- By replacing power diodes with a MOSFET, the LM5050MK-1/NOPB significantly reduces the power dissipation and improves system efficiency.

- The selection of the external MOSFET should be done based on the system's current requirements and the desired efficiency.

5. Typical Applications: The LM5050MK-1/NOPB is commonly used in systems that require multiple power sources to be connected to a single load without reverse current, such as server farms and telecom equipment.

The LM5050MK-1/NOPB provides an efficient solution for power rail management in systems with multiple power supplies, ensuring continuity and reliability of power with its advanced control features. For precise implementation, the latest datasheet should be consulted to get detailed information on the pin functions, typical application circuits, and layout recommendations.
