Other Parts Discussed in Thread: TPS25832-Q1, TPS25830A-Q1
Tool/software:
We would like to develop a USB audio interface to which either a PC / laptop or a mobile device (Android and iOS) can be connected. The connection is designed as a USB-C socket. When a mobile device is connected, it should run in host mode and be charged. If a laptop or PC is connected, it should not be charged.
We are looking for a suitable charge controller for this application. We used the TPS25833Q in the first prototype. Charging the mobile device works, but data communication does not work in this mode. Presumably the mobile device does not switch to host mode. Communication works when connected to the PC via USB-A to USB-C adapter. Is the TPS25833Q unsuitable for our application? If so, do you have a better suggestion? Ideally, the alternative should also allow an input voltage of up to 36V. Charging with 5V / 10W would be sufficient.
