TPS65219: TPS6521901

Abinaya

Part Number: TPS65219

Tool/software:

Hi team,

I use the TPS6521901RHBR version in my custom board. Can this PMIC IC support AM243X LP?

Could you please inform me whether there is a TPS6521901 driver for AM243x or provide some guidance on pmic ic programming driver development?

Which are the steps for programming a PMIC IC?

My doubt is I want to configure the registers through drivers according to the sequence of regulators and configs please help me understand regarding this.

Thank you for your help.

Regards,

Abinaya.

Hi Abinaya,

Have you seen this application report in the TPS65219 product folder? https://www.ti.com/lit/an/slvafk3/slvafk3.pdf

It covers the different TPS65219 variants for powering the AM243x.

TPS65219 drivers are available and are part of the Linux kernel. https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/Documentation/devicetree/bindings/regulator/ti,tps65219.yaml?h=ti-linux-5.10.y

Best regards,

Matt

Hi Matt,

Thank you for the response,

I looked at the application report, and it appears to be informative.

However, in this case, it seems like only the TPS6521904, TPS6521907, and TPS6521908 variants powered with AM243x are mentioned, but not the TPS6521901.

I have attached the TPS65219 variants. According to the attachment in AM243x (ALX), the recommended package is LP87334DRHDR.

We're using the AM243x_lp (ALX) package and the TPS6521901 variants.

Does the Am243x_lp(ALX) package support the PMIC variant TPS6521901?

Hi Abinaya,

The AM243x MCU only supports VDD_CORE=0.85V and TPS6521901 has Buck1 configured to output 0.75V so it is not a good fit. Also, the ALX package does not support VDDS_DDR so you dont need a PMIC rail configured to output 1.1V or 1.2V.

For AM243x in ALX package we recommend using LP87334D. https://www.ti.com/lit/pdf/slda059

Thanks,

Brenda
