Part Number:DRV8847
hi, All.
i've been asked by customer for below question.
please support it.
Q1
correct for below?
in case of 100% TRQ(connect to GND), should Torque be "1"
in case of 50% TRQ(connect to Vext, should Torque be "0.5"
the following sentence is confused.
"Torque is the torque scalar, the value of which depends on the input on TRQ pin. "
it sounds like that there are + polarity figure on TRQ.
there are only 2 thing on Torque such as 1 or 0.5. right ?
in case of 0.5, we can see "0.5" but not for "1" but Torque.
Q2.
what is the Vext ?
there are nothing description about Vext.
should customer use voltage same as VM or any specification ?
Q3.
is it ok if we could make TRQ pin floating if customer doesnt use?.
