Product parameters:

Dual H-bridge motor drive, can drive two DC motors or one 4-wire two-phase stepper motor at the same time;Module power supply voltage 2V-10V;Signal terminal input voltage 1.8-7V;Single-channel working current 1.5A, peak current up to 2.5A, low standby current (less than 0.1uA);Built-in anti-common conduction circuit, when the input terminal is suspended, the motor will not malfunction;Built-in thermal protection circuit (TSD) with hysteresis effect, no need to worry about motor stall  material:

INx is connected to the microcontroller IO or other signal sources, and MOTOR-A and MOTOR-B are connected to the motor.

Precautions:

1. The reverse connection of the positive and negative poles of the power supply will definitely cause circuit damage.

2. When the output is short-circuited to ground or the output terminal is short-circuited, and the motor is locked, the chip will be thermally protected, but the chip will be burned when the voltage is close to or exceeds 10V and the peak current greatly exceeds 2.5A.

Product introduction: Double H bridge, can drive two DC motors at the same time, single channel 7A high power; wide voltage 6.5V ~ 27V; optocoupler isolation input signal; with isolation and undervoltage protection; Relief circuit, stable and reliable, industrial grade. 

Product Highlights:1. Double H bridge, can drive two DC motors at the same time, single 7A current, high power;2. Wide voltage input 6.5V～27V;3. Signal optocoupler isolation input, which can be directly controlled by IO port without interference;4. Under-voltage protection to prevent instantaneous high current from burning the module;

Product parameters:1. The power supply voltage is 6.5V-27V. The power supply must not be reversed or exceed 27V, otherwise the module may be burned. It is recommended to connect a 15A fuse in series at the power input end.2. Dual motor interface, rated output current of each channel is 7A, peak current is 50A, the motor interface must not be short-circuited, it is recommended to connect a 10A fuse.3. The control signal voltage is 3-6.5V, which are the enable signal and the forward and reverse control signals respectively.4. The enable signal terminal (ENA) input PWM adjustable speed, PWM frequency range 0-10KHZ, PWM small pulse width 10us.5. Working temperature -25℃-80℃.6. Product size: 55*55*16mm (length, width and height).7. The diameter of the mounting hole: 3mm. When installing, pay attention to prevent short circuit of the back circuit. You can add insulating pads or copper pillars to raise the circuit board.8. Weight: 20 g.

Suitable motor parameters:A motor with a rated voltage of 24V, suitable for a motor with a rated power of 115W and below or a motor with a rated current of 7A or less for a long time at full capacityA motor with a rated voltage of 12V, suitable for a motor with a rated power of 40W and below or a motor with a rated current of 7A or less for a long time at full capacity

Precautions:1. The power supply of the driver must not be reversed. 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 is overvoltage, the power-on may burn the drive module.2. It is recommended that the rated output current of the power supply be more than 2 times the rated current of the motor, so as not to cause the power supply to fail to provide the current required by the motor to start, and to cause the power supply voltage to drop so that the power supply voltage cannot reach the input voltage required by the drive, so that the drive module performs under-voltage protection shutdown. If the output is cut off, the motor will stop.3. The motor interface must not be short-circuited, otherwise the drive module may be burned. It is recommended to connect a 10A fuse in series at the motor interface.4. When switching between forward and reverse rotation, it is necessary to brake for more than 0.1S before reverse rotation. It cannot be reversed before the motor has stopped, otherwise the driver may be damaged.5. When the drive module is powered off, do not directly or indirectly rotate the motor at high speed, otherwise the electromotive force generated by the motor may burn the drive module. If the application needs to rotate the motor at high speed when the driver module is powered off, it is recommended to connect a relay (NO and COM terminals in series) to the motor interface of the driver, and the relay coil and the driver share the same power supply. In this way, when the power fails, the relay will disconnect the drive from the motor.6. Be careful not to get the driver wet, do not short-circuit the components on the driver board, and do not touch the pins and pads of the components on the board with your hands.
