Hi TI Expert
The latest datasheet declare the power up sequence
9.3.10.1.1 Power-Up Sequence
In a typical system, the VBAT and PVDD supplies are both connected to the vehicle battery and power up at the same time. The VDD supply should be applied after the VBAT and PVDD supplies are within the recommended
operating range.
I want to confirm,
1. if the VDD supply is "before" the VBAT and PVDD, what side effect will be and any work around solution?
2. What is the power up sequence with VDD/VBAT/PVDD and the standby# and mute#?
Regards,
Vincent
