TUSB422: USB connection with phone, charger and microcontroller

Part Number: TUSB422
Other Parts Discussed in Thread: MSP430F5528

Tool/software:

I am looking for a very low-cost small-footprint way to connect a phone, charger and an MSP430 device (MSP430F5528). The microcontroller has a small back up battery and the board only requires a few mA to operate. The phone and/or the charger can be connected at the same time or either can be disconnected. Data rates are a few 10s of kb/s so USB 2.0  data rates are adequate

 

  1.   Is it possible to hard-wire them without any additional controller as in the attached diagram? Can it be done with the addition of  components such as diodes, or a load switch?
  2.  If a controller is needed for USB 2.0, what device is suitable? Is there a reference design or app-note?
  3. Is there a similar reference design for USB-C?

Thanks a lot
