Hello,

I would like to know if you are interested at the ST72141 specifically or the new ST7MC could be interesting for you as well. The new one offers several features and tools helping to speed up the apply.

If 10V (or less) is the motor supply voltage no problem for both the micro to run at your specifics.

The major issues depen on the inverter topology and not on the micro features.

In the same site you find some application notes related with low voltage applications when using these type of micros running BLDC motors.

Let me know for further info or help.

Best regards,

Gaetano
