Motor Driver Boards, Modules

The MADLT11BF motor driver board is a high-performance and cost-effective drive board for DC and stepper motor applications. This board is designed to provide an integrated and easy-to-use solution for high-efficiency motor control. It features a wide input voltage range of 7.5V~30V and a wide operational current range of 0.4A~1.2A.

The MADLT11BF consists of an integrated two-phase full-bridge driver IC and an MOSFET driver circuit, which allows it to operate in both DC and stepper motor mode. In addition, the board has built-in protection against over-voltage, under-voltage, over-current and short circuits. Furthermore, the board features several on-board status LED indicators to show the status of the motor driver.

Application Field

MADLT11BF motor driver board is applicable in a variety of applications, such as home appliances, robots, industry automation, and other applications that require an efficient and cost-effective motor driving solution. The integrated protection circuit and wide voltage and current ranges make this board well-suited for a variety of motor driving application.

Working Principle

The MADLT11BF motor driver board adopts a current mode control scheme. This means that the board constantly monitors and adjusts the motor current to ensure that it is always within the optimum level and that no motor is over-loaded. This is done by monitoring the voltage across a current sensing resistor and using an on-board microcontroller to adjust the voltage applied the gate of the MOSFET.

The MADLT11BF motor driver board also comes with a PWM control input. This PWM signal can be used to control the speed of the motor as well as the direction. The board will convert the PWM signal into an analog voltage signal, which will be used to control the MOSFETs. At rest, the board will output a low voltage, thus keeping the MOSFETs off and preventing the motor from running.

The MADLT11BF motor driver board also comes with advanced features such as temperature protection and current limiting. The board is equipped with an internal temperature sensor that will trigger a thermal shutdown if the temperature of the motor driver exceeds a safe level. This will protect the motor driver from damage due to over-temperature operation. In addition, the board features a current limiting circuit that will lower the voltage across the motor to safeguard it from over-current.

The MADLT11BF motor driver board is an affordable, easy-to-use and highly efficient solution for motor control applications. This board features a wide voltage and current range, advanced protection circuitry and PWM control input to make it suitable for a variety of motor control applications.
