Hello dear ST community,I am making a PPS (sink) application based on NucleoG0B1RE + SNK1M1. As noted in various resources, the TCPP01-M12 doesn't include OCP protection. However, the USB Power Delivery Specification R3.2 on usb.org, strongly recomme...

Hi,I am currently working with the documentation of TCPP01-M12. I have find some small mistake in the table of recommended capacitor C3. The part codes are switched. Also it seems that the GRM188... 0603 package capacitor is obsolete nowadays. Could ...

Hello,I am trying to make my own custom USB PD application on NucleoG0B1RE + SNK1M1 hardware.I want to change dynamically the SNK PDOs in my application (it should be possible according to this post). Since I want it to be working with various Source...

Dear community,I have deployed a basic USB PD sink application according to AN5418 on NucleoG0B1RE + SNK1M1 hardware. I have also implemented a USBPD_DPM_RequestMessageRequest() function inside usbpd_dmp_user.c (according to this post), so the user ...

I have followed this STM wiki tutorial about basic PD Sink. Everything is running according to it, but I am unable to see voltage and current measurement inside UCPD monitor. I have also followed the set-up of debugging button which is working correc...

Thank you for your reply @MROUV.1.Is it the custom OCP solution using the TCPP01-M12 and current sense amplifier with alert pin and another mosfet also feasible, or is switching to the TCPP03-M20 the best path forward in this case?If I move to the TC...

Hello@LLECH.1,You are right after playing with it for a while it seems it would be possible to define multiple PDOs based on the attached PD3_2 Specification. According to the table I could make multiple APDO definitions for 9VProg, 15VProg and 20VPr...

Hello @Nicolas P. ,providing the SNK supported PDOs at the start in pdo_defs.h would also make sense to me. The problem is I dont know the SRC PDOs priory. As this is the case I would like to declare for my 100W SNK general APDO as 3300mV-20000mV max...

Hi @Guenael Cadier,After some time of playing with the code, it does s what I want, so thank you again for your guidance. In the end, there was no need to copy the PDOs from SRC to SNK. I have written my custom functions with help of your advice and ...

Yes I am mainly interested in defining the min/max voltage and max current for the SNK PDO.I want to use my sink as portable programmable power supply and want to support wide range of sources up to 100W. I have also thought about predefining few SNK...
