TUSB422: PD Controller with SBU mux

Part Number: TUSB422
Other Parts Discussed in Thread: TPS65982, TPS25750, TPS65987D

Hi Team,

A customer noticed that the diagram in Figure 2 in the link below requires a PD Controller with SBU mux. Does TUSB422 fits for this application? If not, do we have any device we can use as PD Controller with SBU mux?

  • Hi Danilo,

    Correct a PD controller with integrated SBU mux can be used here. You can also consider using a external mux to control SBU routing. This mux must have 5V tolerant pins. TUSB422 does not integrate a SBU mux. 

    I will loop your question to the PD controller team t see if they have any recommendations. 

  • Hi Danilo,

    We do have a PD controller with an integrated MUX, the TPS65982, but this device is not recommended for new designs. If you are looking for a single port PD controller, I recommend the TPS65987D or the TPS25750 with an external MUX. 

    Thanks,

    Emma
