TPS25810: combination with TPS2547, how to do load sharing?

Part Number: TPS25810

Team,

I have a dual USB charging application with one USB-C and one USB-A port. For this TPS25810 and TPS2547 should be used. Current limitation needs to be as this:

• If only on USB-C a device is connect, current should be limited to 3 A
• If only on USB-A a device is connect, current should be limited to 3 A
• If both ports are connected, limit on USB-C should be 1.5 A and on USB-A 0.9 A

How can this be achieved with ILIM_SET and /LD_DET pins of both devices?

Thanks,
  Robert
