Factory direct sales, high-power dual circuit DC motor drive, stable and reliable, industrial grade

Product highlights:

1. Dual H-bridge, capable of driving two DC motors simultaneously, with a single 7A current and high power;

2. Wide voltage input 6.5V~27V;

3. The signal optocoupler isolates the input and can be directly controlled by the IO port without interference;

4. Under voltage protection to prevent instantaneous high current from burning the module;

5. The high-power TVS and electrostatic discharge circuit suppress transient interference pulses and static electricity, enhance EMC performance, and ensure product stability and reliability, with an industrial grade design.

Product parameters:

1. The power supply voltage is 6.5V-27V, and the power supply must not be reversed or exceed 27V, otherwise the module may be burned out. It is recommended to connect a 15A fuse in series at the power input end.

2. Dual motor interface, with each rated output current of 7A and peak current of 50A. The motor interface must not be short circuited, and it is recommended to connect a 10A fuse in series.

3. The control signal voltage is 3-6.5V, which is the enable signal and the forward and reverse control signal, respectively.

4. Enable the signal end (ENA) to input PWM for speed regulation, with a PWM frequency range of 0-10KHZ and a PWM small pulse width of 10us.

5. Working temperature -25 ℃ -80 ℃.

6. Product size: 55 * 55 * 16mm (length, width, height).

7. Installation hole diameter: 3mm. During installation, pay attention to preventing short circuits in the back circuit. Insulation pads or copper pillars can be added to lift the circuit board.

8. Weight: 20 g.

Suitable motor parameters:

For motors with a rated voltage of 24V, it is appropriate to identify motors with a rated power of 115W or below, or motors with a rated current of 7A or below, which can operate at full capacity for extended periods of time

For motors with a rated voltage of 12V, it is appropriate to identify motors with a rated power of 40W or below, or motors with a rated current of 7A or below, which can operate at full capacity for extended periods of time

Precautions:

1. The driver power supply must not be connected in reverse. It is recommended to connect a 15A fuse in series at the power interface, and the voltage should be between 6.5 and 27V. If the voltage exceeds the limit, powering on may burn out the drive module.

2. It is recommended that the rated output current of the power supply be more than twice the rated current of the motor, in order to prevent the power supply from unable to provide the required current for motor startup, resulting in a drop in the power supply voltage and the power supply voltage not reaching the input voltage required by the driver. This will cause the drive module to perform undervoltage protection, turn off the output, and cause the motor to stall.

3. The motor interface must not be short circuited, otherwise it may burn out the drive module. It is recommended to connect a 10A fuse in series at the motor interface.

4. When switching between forward and reverse directions, it is necessary to brake for more than 0.1s before reversing, and the motor cannot be stopped before it stops
