TDA4VM: The ratio change of PWM

Part Number: TDA4VM

Chpter6.6.5 is not enough to know about PWM feature for me.

Is there any other document which talk about PWM more?

Our customer would like to know how to change the duty ratio of PWM signal.

For example, scheduling the ratio change of PWM in advance, or gradually increase/decrease of the ratio of PWM.

Thanks and Best regards,

HaTa.

HaTa,

There are two styles of PWM in the SoC. The first is in the ICSS module, which is what you're referencing.

There is also PWM feature as part of the Timer IP. This block is easier to use and is what I recommend you look into. It is documented in the section titled "Timer Pulse-Width Modulation".

Regards,

Kyle
