Hi Rick,
thanks for the quick response and sorry for not mentioning the motor type, it is indeed brushed. i have some questions about the DRV8701;
1. looking at the typical schematic, SO is connected back to uC. is the purpose of this pin to monitor the voltage at the output gate?
2. since i am using PWM to control the speed of the motor, I can use IN1 as the control pin is that correct? What would be IN2 connected to?
3. since i need at least 25A continues output current to the motor, can i substitute the 50m ohm resistor with 10m ohm? what type of resistor can i use, and part number suggestion?
4. as for the bulk capacitor, the document mentioned to use a number of them if i understood it correctly is that correct? if so, what determines the number of 10uf to use?
i may have more questions later if you are ok.
thanks again for your help.
