TI中文支持网你好，我想咨询一下bq2598x系列的充电芯片是否都支持QC2.0或者3.0快充。这这个系列的芯片充电时候是否要接到MCU？默认方式是否可行？期待你们的回复，谢谢。
Star Xu：
QC3.0 is a proprietary communication protocol. Therefore, TI has no battery chargers that are standalone compatible with QC3.0. The BQ25890H and BQ25898D plus user designed host software can be configured to work with most QC3.0 adapters as demonstrated in the reference design at TIDA-03029.
All members of the BQ2589X devices with D+/D- pins have compatibility with legacy 5-V USB BC1.2 and some proprietary adapters as well as many high voltage DPC adapters such as QC2.0 adapters.
