Hello Jurry:

GVDD is routed internally. The bypass pin is for external decoupling cap on GVDD LDO.

Best regards,

Tuan

Hi Tuan,

Yes, GVDD is routed internally. Customer wants to know its voltage. In block diagram, GVDD is the internal LDO output.

Hi Tuan,

Nothing wrong. Customer needs to know this voltage to calculate capacitance range. You know it is for auto, customer needs to be sure enough redundancy.

Hi Jurry,

Oh, that's good to know. Anyway, the range is 6.4V min to 7.4V max and nominal is 6.9V.

Thanks,

Tuan
