The MY7605 is a highly integrated QC to USB Power Delivery (PD) controller that supports Qualcomm® Quick ChargeTM 3.0 or Quick Charge 2.0 or BC1.2 or Fast Charger Protocol (FCP) and Smart charge protocol(SCP) technologies to USB PD 3.0 Programmable Power Supply(PPS) specification . It is designed for QC to PD3.0/TYPE-C applications such as power charge cable or power charge board for QC to PD3.0 and etc.

The MY7605 minimizes external components by integrating USB PD baseband PHY, Type-C detection, voltage and vbus short circuit monitors, NMOS/PMOS load switch driver and an 8-bit MCU(8051) to allow small form factor and low BOM cost. MCU so as to facilitate various functions of communication protocol(QC to PD), protections and customized requirements. Supports PD 3.0 Programmable Power Supply (PPS) specification. One-Time-Programmable ROM is provided for program code and user configuration data. The IC allows designer to check USB TYPE-A charge capability and define a USB-C port as a Provider program setup.
