TDA4VL-Q1: question for TDA4V Entry's PMIC Selection

Part Number: TDA4VL-Q1
Other Parts Discussed in Thread: TPS65223

Hi TI team,

Our TDA4V ENTRY design plans to use the PDN-5L solution. I would like to know what the complete order code of the PMIC?

I see that TPS6522311RAHRQ1 is listed in the EVM BOM. The TPS65223 or TPS65221 are mentioned in the J7 SoC power solution. From the draft datasheet of PMIC. I can see that GPIO4 and GPIO5 of 223 have ADC-IN function, but this function is not used in the actual design. So I understand that TPS65221 is ok.

Secondly, I understand that 11 in TPS6522311RAHRQ1 should be the NVM version of PMIC, so should we use 11?

We need to confirm the complete order code as soon as possible for business procurement. Thank you.

Best Regards

    1. Yes, the difference btw PMIC PN 223 vs 221 is the ADC function is supported in the 223 PN only. Please be aware that the ADC function can be used to monitor the PMIC's Tj temp as well as board level voltages. If your system would benefit from measuring PMIC Tj (development stress testing over temp range) then 223 would be the desired PN.

    2. Yes, the J722S EVM SCH & board designs have used the TPS6522311 with NVM ID = 11 for initial wake-up systems.  We have been updating the PMIC to enable it to be more flexible for supporting multiple PDN schemes using same PN TPS6522312 (NVM ID = 12).  The 12 PN is currently under development with PMIC EVM testing new features & flexibility. Once this step is successfully, the new 12 PN will be bench tested on J722S EVM to verify SoC support.  The goal is to use the new PMIC 12 PN for the released J722S EVM SCH & boards.  An applications note entitled "J722S Automotive Power Solutions using TPS6522312 PMIC" is work-in-progress with target completion at beginning of April. The detailed PS6522312 PMIC User's Guide will follow.

    I'm curious why this PMIC (223) has an ADC to monitor the internal junction temperature. Is it because this PMIC generates more heat than other PMICs?

    Hi Juanli,

    In my understanding, this PMIC (223) only a new feature add, because in case you have the need to monitor the PMIC's Tj temp as well as board level voltages,  this will not increase the power consumption or more heat.
