Hi, i have a question about the connections of LS1, LS2 and LS3. In the evaluation board you connected to each pin a shunt resistor and then you filter and amplify the voltage: in this way there are 3 different values, one for each phase. In my application i have space constraint very hard to meet and i can’t use 3 OpAmps. I was wondering if it was possible to short LS1, LS2 and LS3 and use just one shunt resistor and OpAmp in order to read the current.
One more question: is there a minimum value for shunt resistor or 100 mOhm is already the minimum?
Thank you in advance,
