Topics covered include: • Hardware Architecture • PIM Configuration • Board Connectors • User Interface Hardware HARDWARE ARCHITECTURE The dsPIC DSC devices feature an 8-channel, high-speed PWM with Complementary mode output, a programmable ADC trigger on the PWM reload cycle, digital dead time control, internal shoot-through protection and hardware fault shutdown. -
Page 18: Mosfet Pwm Assignment
3.1.1 Power Stage The dsPICDEM MCSM Development Board features two full-bridge inverters to accom- modate a bipolar stepper motor. MOSFET gate signals are powered from a 15V per- manent supply while the full-bridge inverters can be powered from a supply up to 80V. -
Page 19: Amplifier Gain Calculation Formula
PWM shutdown. Each phase current is amplified and then compared with a fixed “safe” current value. A value of 1.7A is set for the dsPICDEM MCSM Development Board; however, the user can change this limit by changing the resistor divider made by R48 and R51. -
