Part Number: TUSB422
Other Parts Discussed in Thread: TUSB1146, TPS25221, TPS65987

Hi,

My customer using Type-C port to output 4  Lanes DP2.0 at alternative mode, and also need support PD output only 5V/900mA,

Could they use TUSB422 + TUSB1146 and one more current limit switch (TPS25221) to achieve this design?

But TUSB422 have no flip pin likes TPS65987 to control TUSB1146, seems need another MCU to control TUSB1146 flip, right?

Or do you have better suggestion for this application? My customer said TPS65987 size to big and no need for 20V power path.

Thanks!

Jeff
