Hello All

I am trying to initialize FET pre driver (MC33937APEK) for the Motor Control Evaluation Board (MTRCKTSPS5744P). 

I followed the initialization procedure (using model based design toolbox for MPC574x). Somehow, I am not able to initialize the pre-driver (model is attached).

Please provide an input for it and where it may be going wrong.

Thank you in advance.

Best Regards,

Abhishek

Hi Abhishek,

Unfortunately, our team does not have such a pre-driver board available, hence we can test the procedure.

The only advice i can provide is to check with an oscilloscope the signals after each step to make sure they are complient with the predriver initialization sequence.

Best regards,
Daniel
