Hello To avoid further issues, I do suggest to change @x70 = xA3 to @x70=x43In this case, only 2 PDOs will be sent as source_capabilities, during PD negotiation.Setting PDOs to 0 while keeping PDO_nb to 5 won't prevent stusb4700 to send out 5 PDOs wi...
HelloSo the behavior is correct: by default, STUSB4700 will advise 5-9-12-15-20V to USBPD sink.If contract is done on 9V for example, stusb4700, thru is monitoring feature, will expect to see voltage increasing to 9V. If not, issue is detected and th...
HelloVs description you are providing, it seems that voltage does not raise as expected so that stusb4700 detects a monitoring issue which explains VBUS_EN_SRC going high.I do not see in the schematic how PD_GPIOx nets are connected to power supply, ...
HelloI suspect a setup issue.To get TypeC connection, the source (i.e the guy who provides Vbus) shall have pull up resistor on its CC pins. While the Sink (guy who draw power) shall have pull down on its CC pins.When Sink connect a source, it create...
Hello GeraldAs stusb1600 is in DRP configuration, without any cable connected, I do expect to see CC toggling between ~3V and 0vBy default, Rp is setup to advise 3A so when Sink is connected, I expect to see 1 CC pin at ~1.6V. If CC are zero when con...
