TMC223-SI

TMC223 is an integrated stepper motor microstep control, Drive, RAM, OTP memory and the company's patented StallGuard features together with high-performance chips. RAM or OTP memory is used to store motor parameters and some configuration parameters. The TMC223 itself has a maximum of 16 times subdivision and a drive current of up to 0.8A. It communicates with the microcontroller via a 2-wire serial interface. Only a cheap microcontroller and TMC223 can be used to form a complete single axisThe stepper motor controls the drive system.

●Motor driveaspect

◆ Drive a single stepper motor with a 4-step resolution microstep subdivision, including the maximum number of subdivisions of the whole step 16

◆Programmable control coil current max. 0.8A provides drive voltage range from 8V to 29V

◆ Fixed frequency PWM current control with automatic selection of fast and slow decay mode

◆The whole step frequency is 1KHz

◆High temperature, open circuit, short circuit, over current and under voltage diagnosis

●Motor motion controlaspect

◆ Built-in 16-bit position counter

◆Configurable speed and acceleration settings

◆ Waveform generator can be automatically configured according to the selected position or speed control mode

◆Change the target position in time during motor movement

◆External reference signal input and output, can be used as motor limit signal

● 2-wire serial interface

◆Transmission rate 350KBPS

◆ can transmit diagnostics, status information and motion parameters

◆Programmable node address number 32

● Stall detection without external sensor

◆Can detect motor overload to avoid losing step

◆ Monitor the vibration of the system and solve the resonance problem in a targeted manner
