Hi, I have a customer asking if we can drive with CCU6 at least one of the low side transistors during commutation between blocks. They believe that they need this for EMI constraints. The application is controlling a 3 phase motor.
Is it possible to do this with the Multichannel feature in order to modulate the low channel during the block commutation?

Thanks

Hello,

Yes, the multichannel mode (MCM) can be used to modulate all 6 timer 12 outputs of the CCU6.
For example, the following application note describes the control of a BLDC motor using the MCM mode.
