1 This shows the shoot through on the motor driver
This shows the shoot through on the motor driver.  You can see the shoot through happens during a pause in the PWM signal.  We also monitored the FAULT pin on the driver and that did not go low during the current spike. Green = driver input voltage Yellow = sense resistor current Purple = top PWM Blue = RESET

2 We added more ceramic capacitance on VCP
Green = driver input voltage Yellow = sense resistor current Blue = top PWM Note VCP peak to peak is reduced to 3.4Vpp. However you can still see shoot through.
