Other Parts Discussed in Thread: TPS659037, BEAGLEBOARD-X15

Hi All,

My customer is analyzing AM57x solution. But there is a question about this EVM.

In the sch, the PMU is TPS659040. But in EVM picture, the IC is TPS659039. In addition, the document is TPS659037 and said replaces TPS659039.

So, customer should using TPS659037 and using TPS659037 for all design such as Boot setup? Thanks.

Hello Martin,

"But there is a question about this EVM." - Do you have in mind BeagleBoard-X15 EVM or another board?

So, customer should using TPS659037 and using TPS659037 for all design such as Boot setup?

- Yes, correct. TPS659037 is dedicated PMIC for AM57xx devices. See the AM57xx Data manual:

However, TPS659037 is the newest device in TPS65903x PMIC family. Therefore on your costumer EVM the PMIC is TPS659039.

Please take a look on following patches for PMIC:

Best regards,

Yanko
