Hi,
Customer reported issue about TPS2547 OUT abnormal.
Can you help to check the waveform and behavior is correct or not? And customer want to know when EN pin went High, OUT got high / low transition, does TPS2547 configured as fast charge or normal charge?
Hello Randy,
Thanks for posting your question here on E2E. For the community, here is a picture of the screenshot in question
So this is normal behavior for the TPS2547. When EN is pulled low or high, OUT will follow. As far as the charging, when the TPS2547 is in DCP_AUTO mode, it determines the type of portable device it is connected to in order to supply the max amount of current possible. This is why VBUS drops as seen and the feature is explained within the schematic.
The TPS2547 has the ability to source a maximum of 3.0A as shown in the datasheet
