TPS65224-Q1: [TPS6522x12-Q1] PMIC Resource selection query

Part Number: TPS65224-Q1

Hi TI,

on document which is "J722S/AM67x/TDA4VEN/TDA4AEN Processor Automotive Power Designs using TPS6522312-Q1 PMIC"

If we set RS0 to GND, is it right LDO2 is for SD Card supply?

I understood

 1) RS0: 0 set -> LDO2 for SD Card

 2) RS0: 1 set -> LDO2 for efuse supply

but below power map is vice versa.

which setting is correct, if we want to use LDO2 for Efuse Prgm?

best regards,

    Hi Jihoon,

    Thank you for reporting this mistake. I will communicate this to the engineer responsible of this document. The table 10 information is incorrect so you can follow this guide:

     1) RS0: 0 set -> LDO2 for efuse supply

     2) RS0: 1 set -> LDO2 for SD Card

    I also confirmed this functionality on our EVM.

    regards,

    Niko
