TAS5534 Power-up Sequence for I2C

Sadanori Kato
Guru 36540 points


Hi,

We would like to confirm the power-up sequence for I2C as below.
Is there the possibility that an abnormal current and a reverse voltage occur in that case if the scl and sda are connected to the power line(MVDD) of the uC by the pull-up resistors?
Should those resistors be connected to TVDD if it is problem?
Could you please give us your advice for this issue?

Best Regards,
Kato
