PWM control via microcontroller
There is a number of different microcontrollers available, which provide specific BLDC commutation
units. However, the TMC603 is designed in a way in order to allow BLDC control via standard
microcontrollers, which have only a limited number of (free) PWM units. The following figure shows
several possibilities to control the BLDC motor with different types of microcontrollers, and shall help to
optimally adapt the TMC603 control interface to the features of your microcontroller. The hall signals
and further signals, like CURx interconnection to an ADC input, are not shown.
