TDA2EG-17: Ask about TDA2E Power Supply Sequences

Jack Li

Part Number: TDA2EG-17
Other Parts Discussed in Thread: TDA2E, TPS65919-Q1, LP8733

Hi team,

My customer is using the TDA2E platform, the solution is PMIC(TPS65919)+SOC: TDA2EGBHQCBDQ1, they find two power sequence and don't know how to select, please help to answer it, or could you please provide TDA2E Power Supply Sequences, thanks!

The left TPS65919-Q1 Power Management Unit (PMU) for Processor datasheet (Rev. A) :

Hello Jack,

I may not be completely understanding the question. But ... the first link is for the generic datasheet for PMIC. The 2nd link is for how to use the PMIC to connect to the TDA SoC.

Do they already have systems designed and built? Or are they designing a new system?

Thanks,

Kyle

Hi Kcastille,

Could you please share the off to active power sequence to us, my customer's system is PMIC(TPS65919)+SOC: TDA2EGBHQCBDQ1. Thanks in advance!

Best Regards!

Jack,

Apologies as I misread the original question. The 2nd link that points to TPS65919 for DRA78x/TDA3x is for a different SoC in the Jacinto 6 family.

The best/recommended reference is to the TDA2Ex-17 EVM (aka DRA71x EVM):

DRA71XEVM

download DRA71x/DRA79x/TDA2Ex17/AM570x CPU Board Schematic Rev D (Rev. B)

The PMIC power supply solution is built around the LP8733 and LP8732 PMICs.

Kyle
