USB PD in STM32L562

NITHIN · ‎2024-03-26

Hi Team,

I need to build USB PD program on ST32L562, The voltage they are expecting is up to 45V. How to do this?

Regards

Welcome @NITHIN, to the community!

~~USB PD currently defines a maximum voltage of 20V, so the expected 45V cannot currently be achieved with USB PD without detours.~~

Correction: with the new specification for USBPD PD 3.1, a new voltage range is available in EPR mode (Extended Power Range). In contrast to SPR (Standard Power Range), EPR can now also negotiate 48V at 5A = 240W, provided a suitable USB PD source is available. ST is currently developing the appropriate hardware for sink and source.

Hi Peter,

Can i use a voltage divider ckt or a voltage regulator to achieve this?

Hi Peter,

which all boards are available in the market with inbuilt EPD?

Is STM32L562 evaluation kit, a good option?

Peter (or any ST Employee),
I want to be clear. As of 6/18/2024, are there any STM32 devices that support the EPR 240W Sink capability?

@jrm please see this thread Solved: Re: USB PD sink - STMicroelectronics Community, where @Nicolas P. gave an outlook.

Hello @jrm

to rephrase the link shared by @Peter BENSCH : All STM32 devices with the UCPD IP inside (G0, G4, L5, U5, H5, H7RS), thanks to the protocol provided in the USBPD library, support EPR 240W, sink or source, or even DRP. But there is no hardware board available yet, to demonstrate all this power range for all sink / source combination.
