Hi team
I would like to ask a question that about the function block diagram:

The power supply showed is 'VDD'. From my understanding, the VDD could be the 12V automotive battery + Anti-reverse diode and then input to the VDD pin. Here my questions are:
1. When the car is in start-stop condition, which means the battery may drops from 12V to 6V or boost to like 18V, so to the chip's power supply is not stable, the VDD is not a constant value. Will this phenomenon affect the vibrator performance?
2. Could you please share some instruction or documents for this application scenario? Or what content should I refer to according to the worry from customer? Customer need to know if the vibrator will have the same performance compared to a constant supply voltage, and also would like to know if so what block inside the chip could help to do this to keep the vibrator performance same, thank you.
