Normally when designing single axis stepper system to select respectively, design control part, drive part and power tube of the three parts tend to be independent, it is necessary to design and develop the parts. And the development of TRINAMIC company TMC223 the chip integrates the function of control, drive function and drive pipe, greatly reduce the development time and money as well as reduce the volume of products, and to enhance the functionality. TMC223 is an integrated stepper motor microstep control, drives, RAM, OTP memory, and the company's patented technology StallGuard functions with a high performance chip. RAM or OTP memory used to store the motor parameters and some configuration parameters. TMC223 itself with maximum 16 times segmentation, drive current can reach 0. 8 a, through the two wire serial interface with micro controller communication, need only a cheap microcontroller and TMC223 can form a complete single axis stepper motor drive control system. TMC223 chip constitute the single axis stepper motor drive control system, the system only requires two main chips, all the movement function including waveform generator, pulse generator. Drive function includes PWM and power drive and other major functions are implemented by TMC223, external direct connect two phase stepper motor, and the microprocessor is responsible for the communication and send TMC223 instruction, compared with the traditional way greatly alleviate the burden of the microprocessor, it can be free to do a higher level of development such as I/O control, etc. The system of peripheral circuit is simple, strong anti-jamming capability, high reliability, reduce system of capital. Because the whole system only need two chips can do volume is small, can be used in limited space, such as security yuntai and instrumentation, automotive electronics and many other fields. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
