Part Number: DRV8662

Hello.

I want to ask about DRV8662 input.

Can the DC voltage be applied to the input (IN + / IN -) of the DRV 8662?

If the input contains a bias circuit for AC coupling, is AC input only?

Also, can input variable duty input of DRV 8662 other than duty 50%, for example 10% to 90%?

It is to make the output of the DRV 8662 variable.

Regards.

Hi k-hashi,

Yes, you can input a DC signal into the DRV8662.

In section 8.4.1.1 of the datasheet, we only refer to the 50% duty cycle to make sure that the waveform is starting and stopping at a differential voltage of 0V. When we refer to playing the waveform, the duty cycle is expected to be changed. Changing the duty cycle from 10%-90% is expected when varying the output.
