EVSPIN32F0251S1, in the schematic, what is the function of U3. When is it used.

[Enrico Poli · Accepted solution]

U3 is a quad comparator.

It is used for overcurrent detection (page 1 of the schematic) and the BEMF zero crossing detection circuitry (page 2).

[ADani.2]

So when I use FOC, should I set jp6 jp7 jp8 as 2-4 or use U3 and set them to 2-1.

thank you,
