How to Use MOSFET Drivkort 4-kan 50V 10A: Examples, Pinouts, and Specs

The MOSFET Drivkort 4-kan 50V 10A (Manufacturer Part ID: EKM014 - UCC27524) is a 4-channel MOSFET driver board designed by Electrokit. It is capable of handling up to 50V and 10A per channel, making it ideal for controlling high-power loads such as motors, LEDs, and heating elements. This driver board allows low-power control signals, such as those from microcontrollers, to efficiently drive high-power devices.

• Driving high-power DC motors
• Controlling high-current LED arrays
• Switching heating elements in industrial applications
• General-purpose high-power switching in automation systems
• Interfacing with microcontrollers like Arduino, Raspberry Pi, or other logic-level devices

The following are the key technical details of the MOSFET driver board:

The MOSFET driver board has the following pinout:

1. Power Connections:

   • Connect the VIN pin to the positive terminal of your load power supply (up to 50V).
   • Connect the GND pin to the ground of your load power supply.
   • Connect the VCC pin to the power supply for the logic signals (3.3V or 5V).
   • Ensure that the ground of the logic power supply is connected to the ground of the load power supply.

2. Control Signals:

   • Connect the control signals (e.g., from a microcontroller) to the IN1, IN2, IN3, and IN4 pins.
   • Use 3.3V or 5V logic levels to control the MOSFETs.

3. Load Connections:

   • Connect your load (e.g., motor, LED array) to the OUT1, OUT2, OUT3, and OUT4 pins as needed.

4. Testing:

   • Apply the appropriate control signals to the input pins and verify that the load is switching on and off as expected.

• Ensure that the load does not exceed the maximum current rating of 10A per channel.
• Use proper heat dissipation methods (e.g., heatsinks) if operating at high currents for extended periods.
• Avoid short circuits between the output pins and ground or power supply.
• Use decoupling capacitors near the power supply pins to reduce noise and improve stability.

Below is an example of how to control a motor connected to Channel 1 using an Arduino UNO:

// Define the control pin for Channel 1
const int controlPin1 = 9;

void setup() {
  // Set the control pin as an output
  pinMode(controlPin1, OUTPUT);
}

void loop() {
  // Turn the motor ON
  digitalWrite(controlPin1, HIGH);
  delay(1000); // Keep the motor ON for 1 second

  // Turn the motor OFF
  digitalWrite(controlPin1, LOW);
  delay(1000); // Keep the motor OFF for 1 second
}

1. The load is not turning on:

   • Verify that the control signal voltage matches the logic level (3.3V or 5V).
   • Check the power supply connections for both the logic and load sides.
   • Ensure that the load is properly connected to the output pins.

2. The MOSFET driver board overheats:

   • Ensure that the load current does not exceed 10A per channel.
   • Use a heatsink or active cooling if operating at high currents.

3. The load behaves erratically:

   • Check for noise or instability in the power supply.
   • Add decoupling capacitors near the power supply pins.

4. The board does not respond to control signals:

   • Verify that the ground of the logic power supply is connected to the ground of the load power supply.
   • Ensure that the control signals are properly connected to the input pins.

Q: Can I use this board to control an AC load?
A: No, this board is designed for DC loads only. For AC loads, consider using a relay or a solid-state relay.

Q: What happens if I exceed the maximum current rating?
A: Exceeding the 10A per channel limit can damage the MOSFETs and the driver IC. Always ensure that your load stays within the specified limits.

Q: Can I use this board with a 12V logic signal?
A: No, the logic input voltage must be between 3.3V and 5V. Using higher voltages can damage the driver IC.

Q: Is it possible to control all four channels independently?
A: Yes, each channel has its own control input, allowing independent operation of all four channels.
