WebFeb 14, 2013 · I am following an application note by Microchip called AN857: ww1.microchip.com/downloads/en/appnotes/00857a.pdf The other MOSFET in the circuit IRLI3705 I understand. I give the gate a voltage (12V) and the drain to source conducts current. When I don't give it a voltage then it does not. WebAN857 Brushless DC Motor Control Made Easy Author: Ward Brown ment. The final code can then be ported to one of the Microchip Technology Inc. smaller, less expensive, PIC microcontrollers. The porting takes minimal effort because the instruction set is identical for all PIC 14-bit core devices.
