Hi,

How do I change drive board from 42V to 52V of MTRCKTSBNG128 development kit?  Drive board has FET driver MC33937A.

Thanks!

Hi john,

MTRCKTSBNG128 contains two boards.

Board with MCU is designed for powering up to 18V (MC33905 is designed for supply voltages up to 28V).

Board with MC33937A FET driver could run up to 58V. You need at least modify voltage dividers. See 3-Phase BLDC/PMSM Low Voltage Power Stage User Manual​ for DC Bus voltage and Back EMF signals voltage dividers.

I hope it helps you.

Have a great day,
RadekS
