MDDDT3530P Datasheet/PDFThe MDDDT3530P is a motor driver board, or module, specifically designed for motion control applications. It integrates multiple hardware peripherals, such as drive power switches, optocouplers, and protection circuits, in a single board, making it an ideal choice for IC Products and motion control applications.
Application Field
The MDDDT3530P is designed for controlling various motor applications, such as motion control systems and precision positioning systems. The board is ideal for controlling stepper motors and DC brushless motors. It features a maximum output current of 4A and can be used with a wide range of input voltage from 8 to 35VDC. The device offers comprehensive protection functions, such as under voltage lockout, over current protection, short circuit protection, etc.
In addition, the MDDDT3530P can be used with a range of motion controllers, making it a perfect choice for motion control applications, such as robots, printing machines, AGVs and automated line applications. Furthermore, the device supports various communication protocols, such as CAN bus, 1-Wire, RS-232/485, I2C and SPI, providing a flexible platform for communications between the motion controller and other components connected to the board.
Working Principle
The MDDDT3530P features a PWM control mode. This control mode takes advantage of the fact that the average voltage level of a pulse width modulated (PWM) signal reflects the duty cycle of the waveform, and thus the speed or torque of the connected motor.
In practice, the MDDDT3530P works by receiving a PWM signal from the motion controller as an input, and outputting a PWM signal with a higher frequency to the motor driver. The frequency of the PWM signal is adjusted according to the duty cycle of the PWM input, which in turn affects the speed or torque of the connected motor.
Additionally, the MDDDT3530P features an optocoupler protection circuit, which protects the motor driver from over-voltage and short circuit conditions. The protection circuit works by monitoring the voltage level of the output signal and automatically shutting down the device in the event of an over-voltage or short circuit condition.
