switching needs to be more smooth to avoid overload which drops vbus.After vbus drops, system needs to restart from 5V otherwise there will be no contract
It can be that switch closure generates undershoot on VBUS_VS_DISCH pin so that stusb4500 detaches.If at same time CC pin goes to high level, it means it was overshoot (over voltage detected) otherwise, it is undershoot.Having vbus_vs_disch pin volta...
HelloWhen using SPST system might have difficulties to see detach properly and so to restart attachment + power nego properly.As per TypeC spec, when detachment occurs, VBUS shall discharge down to below 0.8V on source side and within vSafe5v on sin...
HelloI'm used to change PDOs on stusb4500 and I never faced issues.Many customers modify also our default settings, to fit their application, without any issue.To trace protocol, you need to insert protocol sniffer or to use oscilloscope able to deco...
