Hi ,

Could you consider the TPS25840-Q1 which including the DCDC 5V output and data communication function ?

Hi,

honestly I haven't thought about using BC1.2 yet. But I see that this is the wrong type of controller. I need the EMI-protection for an usb-device. The chip you have suggested is for an usb charging port, isn't it?

At the moment I think of surge, burst and perhaps short circuit or over voltage protection. I know how to build it with discreet parts, but perhaps there is an option for an integrated module and this would be the better way.

Best regards, Jens Herrgesell

Hi,

Yes, the TPS25840-Q1 is for USB charging port .

So the TPD3S014 can meet your requirement or not ? The TPD device can do the ESD protection in dataline (DP/M) but it don't have the EMI function.

You mention should have the surge, burst and OVP. You can refer to TPD3S716 for study.

We have any other part TPS254900-Q1 which for the BC1.2 type A port solution, also have the OVP and ESD function in the dataline.

Hi,

I think the TPD3S716 fits perfectly.

Thanks a lot for you help.
