Hello,I am using the STM32 USBPD Library in a DRP battery bank application, and want to reduce idle power consumption. In the documentation and source files, there is mention of a usbpd_lowpower.h file but I cannot find this file anywhere.There is a...

Hello,I am using the TCPP03-M20, and would like to save space/cost by combining the Source and Sink path into one mosfet gate pair.The datasheet provides an example of a combined source/sink path using two Schottky diodes and a 1M resistor with the s...

Hello,I have a custom board setup with an STM32G071GBUxN and a TCPP03-M20.I have followed this STM guide for setting it up as a DRP device.It is able to negotiate as a sink with Source only devices, and it is able to communicate over LPUART1 to show ...

Hello,I am implementing a DRP device that is to be connected to a battery.I have this DRP example setup with the X-NUCLEO-DRP1M1 and a NUCLEO-G071RB. It is working with a 5V profile and a fixed 5V supply.I have added a 9V source PDO in CubeMX, and ca...

Thank you!

It seems as though the TCPP03-M20 has a built in hardware check to prevent the consumer and provider paths to be open at the same time.When I write 0x14 to to register 0, the ack register never updates to 0x14, but instead stays at 0x18. I have remov...

From testing, it seems as though the consumer gate driver cannot turn on if there is no voltage on VBUS. Is this a hardware limitation of the chip?I am thinking I can get the system to work with the following single power path layout below and some t...

Hello,I have since moved away from using the GUI portion of UCPD library to save flash. It would take a fair bit of setup for me to reproduce the issue, and this is no longer a roadblock for me. Thanks,Nate

I can check this later this week.I have gotten the majority of my project working without this debugging functionality however, so this isnt as much of a priority for me.Nate
