AX9291Q-USB Dedicated Charging Port Controller


AX9291Q-USB Dedicated Charging Port Controller for Fast Charging Protocol and QC 2.0/3.0 DataSheet
(Support   DCP / BC1.2 Apple  / Samsung AFC Qualcomm  QC2.0/ QC3.0 HUAWEI FCP AEC-Q100)

GENERAL DESCRIPTIO
TheAX9291Qis a fast charging protocol controller for HiSilicon Fast Charging Protocol
(FCP) and Qualcomm® Quick ChargeTM 2.0/3.0 (QC 2.0/3.0) USB interface. TheAX9291Qmonitors USB D+/D− data line and automatically adjusts the output voltage depending ondifferentpowered device (PD). The charging time of PD is therefore optimized by theAX9291Q.
AX9291Qcan support not only USB BC compliant devices, but also Apple / Samsung /HUAWEI devices and automatically detects whether a connected powered device is QC 2.0/3.0or FCP capable before enabling output voltage adjustment. If a PD is not compliant with QC2.0/3.0 and FCP, theAX9291Qwill disable the adjustment of output voltage and keep the default5V output voltage for safe operation.
TheAX9291Qis available in a space-saving SOT-23-6 package.
