Part Number: TPS2511
Other Parts Discussed in Thread: TPS25810

Is it possible to use a IC like TPS2511 to charge USB-C devices (Smartphones) with a maximum of 300mA ?

What ICs would work best for that?

Yes you can program the TPS2511 to have a low maximum current through the use of the ILIM_SET pin. You can reference Figure 25 in the datasheet for what resistance you should use

Thank you for your answer.

Yes,i know i can set this ILIM, but does that really works?

Is it enough to connect CC1/CC2 Pins with 56k Pullup to VBUS?

Thank you!

Are you conencting to a Type-C port? If you are wanting a Type-C port controller, I would recommend the TPS25810. However, if you are connecting to a Type-A port, but want to be able to support Type-C devices, you can use the TPS2511. The CC pullup resistors will be placed within the Type-A to Type-C cable.
