Hi Community,
I designed and developed a board for STUSB4500. I followed the schematic as mentioned in the STEVAL-ISC005V1 schematic diagrams, however I used only the main circuitry surrounding STUSB4500. There is no particular guidelines for layout, so I assume that is not the problem. Even in the main circuitry I only used only one output and not connected PowerOK2 and PowerOK3 pins rather given only test points just in case. I have attached the schematic for your reference. NOR Gate, BMS Shutdown switch, Button Operation LDO and Timer components can be ignored as there is no interconnection between PD controller and these components.
When i'm connecting type C input, the VBUS_VS_DISCH pin is reading 5V and the gate pin of Power MosFETs are at 0.6V and i'm not getting output. The voltage reading at VBUS is 5V.
Also in the STEVAL-ISC005V1 schematic, the VSYS pin is connected to 3V3 of Voltage regulator. So I have added an LDO in schematic but haven't soldered it in PCB. The reason for not soldering is that in datasheet it is written that VSYS pin is a output pin.
