Pulse Width Modulator for Motor Control (PWMMC)
9.3 Features
Features of the PWMMC include the following:
• Three complimentary PWM pairs or six independent PWM signals
• Edge-aligned PWM signals or center-aligned PWM signals
• PWM signal polarity control
• 20 mA current sink capability on PWM pins
• Manual PWM output control through software
• Programmable fault protection
• Complimentary mode also features:
– Dead-time insertion
– Separate top/bottom pulse width correction via current sensing
