Hey guys,
So I am trying to wire up a circuit to drive a brushless motor using the tb6575fng ic. I'm not very experienced in electrical engineering but seem to be learning new things everyday. Regarding this ic, my question is: In the data sheet on page 13, in the example, at pin 23, there's a device called a comparator. Can anyone interpret what it is being used for and if it's necessary for the circuit? Is it possible I can wire the three phases of the motor straight to pin 22 (with the resistors) without the comparator? Also why is the comparator connected to input pin 22 as well? Why is pin 22 connected to the grounds of the low side transistors? All input is helpful and appreciated!
