Tool/software:
IN our config, we supply power via tow different source, to the BQ25792. One of those sources is a 12V supply. The other source is the '750.
We have Vin_3V3 connected to the PCBA 3.3V rail.
If the '750 doesn't see a USB-C signal, and no power on VBUS, then the device reports always in PTCH mode. If we connect a USB-C PD to the '750, then the firmware loads from the EEPROM, and the device goes to APP mode.
Hi Kevin,
Thank you for reaching out!
I would like to highlight our follow-on device, the TPS25751, recommended for all new designs. This device is pin-to-pin compatible with the TPS25750 and addresses known issues with battery charger control on the TPS25750. Please see the following FAQ for more information.
Best Regards,
Aya Khedr
