Hi, Team

One of my key customer, KyungShin is asking reference code for TPS65381A-Q1.

we understand there is GUI for EVM.

Customer has to code to bring up or else. Can you provide reference? Thanks.

Hi Luke,

I am not aware of any reference code for this PMIC. There may be some reference code in the TMS570 MCU libraries. For the EVM you will also need a TI-GER board, I believe you can order one at the link below

https://www.ti.com/product/TPIC8101EVM/part-details/TPIC8101EVM

Besides that, they should be able to control the PMIC with the appropriate SPI reads and writes as described in the datasheet.

Hope this helps.

Best,

Michael Hernandez

HI, Michael

Thanks for your comments.

I understood we don't have reference code. is there any flow chart to bring up this PMIC? or state machine to read/write by SPI?

Hi Luke,

There is a diagram in the datasheet

By default, the PMIC will eventually settle into the Safe state. The PMIC can only be configured when in the diagnostic state. You can stay in the diagnostic state by setting the diagnostic state mask. After completing configuration of the PMIC you can then transition to the active state.

Hope this helps.

Best,

Michael Hernandez
