Need help on PMIC and battery capacity - EPOS reference design

Aravind .R

Other Parts Discussed in Thread: TPS65910A, AM3352, AM3359

Hi All,

I want to design EPOS based on already existing ready solution from TI. I checked completely the details, i am not able to find the battery current capacity & battery part number of 7.4V & 3.4V batteries used in the design, pl let me know from where i can get it.

As i am planning to use 9V adaptor, do we have any PMIC for AM3352 with input voltage of 10V, i checked with TPS65910A but it is having only 5.5V.

Kindly help me on the same

Regards,

Hi Aravind,

Our hardware engineer is currently on vacation, so I'll forward this to the factory team.

Best regards,
Miroslav

Here is the link to AM335x power solutions.

There is no AM335x companion PMIC which can support 9V input voltage. A step-down converter needs to be used for converting 9V to a voltage range supported by companion PMICs. In AM3359 Industrial Communications Engine reference design, TPS5420D is used for converting 24V board input to 5V TPS65910A3 input voltage. The schematic is available at here.
