Part Number: AM3352
Other Parts Discussed in Thread: TPS65910

Hi Support Team,

The following voltages are applied to the VDDSHVs of AM3352.

VDDSHV1,2,5: 1.8V
VDDSHV3,4,6: 3.3V

3.3V is taken from a different IC from TPS65910,
The rise time of 3.3V is about 2ms faster than 1.8V.

The CPU is operating normally with the current settings,
but the datasheet seems to indicate that 1.8V => 3.3V is appropriate.

Can you please confirm that there is no problem with the above usage?

Best Regards,
Kanae

Hello Kanae

Thank you for the query.

Can you confirm if the below sequence is being followed.

Hi Sreenivasa,

Thank you for your reply.

Even if it is currently operating without problems, it may cause problems
if the specifications are not followed, so I would ask the customer to modify it
as per the power sequence described in the data sheet, without exception.

Best Regards,
Kanae
