Instructions for Using L298N
Power Supply Connection:
- Connect the logic supply voltage (5 V) to the
Vss
pin. - Connect the motor supply voltage (5 V to 35 V) to the
Vs
pin. - Ensure that both power supplies are properly decoupled with capacitors to reduce noise.
- Connect the logic supply voltage (5 V) to the
Motor Connections:
- Connect the motor leads to the output pins
Out1
,Out2
,Out3
, andOut4
. - Each pair of output pins (
Out1
andOut2
,Out3
andOut4
) can drive one motor.
- Connect the motor leads to the output pins
Logic Input Connections:
- Connect the logic inputs
IN1
,IN2
,IN3
, andIN4
to your microcontroller or control circuit. - Use these inputs to control the direction of the motors:
IN1
andIN2
control the first motor.IN3
andIN4
control the second motor.
- Set the inputs as follows:
- Forward:
IN1
= High,IN2
= Low (or vice versa for the second motor) - Reverse:
IN1
= Low,IN2
= High (or vice versa for the second motor)
- Forward:
- Connect the logic inputs
Enable Inputs:
- Connect the enable inputs
ENA
andENB
to control the enable state of the outputs. - Set
ENA
andENB
to high to enable the respective channels. - Set
ENA
andENB
to low to disable the respective channels.
- Connect the enable inputs
Thermal Considerations:
- Ensure proper heat dissipation by mounting the L298N on a heatsink if driving high currents.
- Monitor the temperature to avoid overheating, which can trigger thermal shutdown.
Overcurrent Protection:
- The L298N has built-in overcurrent protection, but it is advisable to use external fuses or current-limiting resistors for additional safety.
Testing:
- Before connecting the motors, test the L298N with a simple load (e.g., a resistor) to ensure correct operation.
- Verify the logic inputs and enable states using a multimeter or oscilloscope.
By following these instructions, you can effectively use the L298N to control DC motors or stepper motors in your projects.
