Hi Jeon,

TI automotive device's minimum operate voltage is 4.5V, we can not support 3.3V PVCC operation supply.

4.5V is enough for auto application.

Could you please tell me why you need 3.3V operation supply?

Thanks!

Regards,

Derek

Hi, Derek

It is not necessary to use 3.3V. You can use 4.5V or 5V.
Are there any products that satisfy all of the above specs?

Thanks,
