Dechun,

Hi, the user guide for the TPS659413-Q1 and TPS659411-Q1 is located here: http://www.ti.com/lit/pdf/slvubr0

This includes how to connect the devices to the processor as well as the default settings and sequencing for both devices.

Please let me know if you need anything else.

Thanks,

Nastasha

Hi Nastasha

Many thanks for your document!

Also what software tools and hardware tools we need to prepare for programming the TPS65941x before the system power up?If TI can provide these tools? How can I get these tools？

Can TI set the power-on sequence according to different customer requirements before the sale?

Many thanks

Dechun,

The TPS659413-Q1 and TPS659411-Q1 are programmed specifically for TDA4VM and J7 requirements. Custom solutions with the TPS6594-Q1 are not yet available. Please reach out to your local sales representative if you are looking for something specific. We also have EVMs for the TPS6594-Q1 devices but you would need to reach out to your sales representative to request any hardware tools. If you are designing a platform with J7 or TDA4, we recommend requesting the J7 EVM to evaluate both the PMICs and processor.

Thanks,

Nastasha

Hi Nastasha

Did TI program NVM to make TPS659413-Q1 and TPS659411-Q1 suitable for TDA4 before providing it to customers? We didnt found the Bulks and LDOs default NVM value from the datasheet and user guide.

Dechun,

Yes, TI programs the devices before shipping them. The settings for the devices are not located in the datasheet, they are located in our user guide for TDA4: http://www.ti.com/lit/pdf/slvubr0

Thanks,
