Other Parts Discussed in Thread: DRV8302
To whom it may concern,
I have three questions about the DRV8302-HC-C2-KIT current sensor. At first, when I saw the schematic, I wonder why 1 current shunt sensor(Ic) go through other circuit. On the other hand, 2 shunt current sensor(Ia and Ib) go through the DRV8302's current amplifier. Is there a reason that make this?
Secondly, each current sensor result goes MCU's two ADC ports. I wonder why the each signal goes to two ADC port. Manual describes for measurement accuracy. But, I don't know how it can make improve the measurement.
Lastly, I wonder where each phase sensor (shunt current sensor and voltage sensor) ADC value(0~4095) correspond to real current and voltage value range. In other words, what that sensors measurement range is. I hope to solve the questions. Thanks for reading my questions. Also, for your understanding, I attach the some pictures. I look forward to your reply.
Yours faithfully
