The PPHV line is always off.
I have conected VBUS and VBUS_IN from the USB C Connector to the TPS25750D. also CC1 and CC2. At I2Cm there is a CAT24C256 I2C memory. Every other pin is conected to GND except VIN_3V3, LDO_3V3 and LDO_1V5. PPHV is the output witch is connected to a autonomous DC / DC Converter with 4 V to 30 V Input range.
In my application there should be an output voltage in every case a USB Connection is atablished. If there is an PD able source there should be a contract to 20V / 60 W. If the PD Source is to weak, then the maximum that is available.
I took a binary with theTPS25750 Application Customization Tool and flashed it with the totalphase flash center to the I2C memory. The TPS25750D seems to read out the memory at start up, but afterwards there is no voltage at the PPHV output. If I connect a PD able power supply there is some data trafic at one CC line but also no output voltage.
What do I wrong?
Application Customization Tool:
what effect the questions 5 to 8 ? What the difference between generate low region binary and generate full flash binary?
please give me an advice to fill out the form corectly for my application.
