OB2613x

GENERAL DESCRIPTION

OB2613X is a highly integrated secondary-side  fast charging controller that supports USB PD3.0 including programmable power supply(PPS) mode, Huawei FCP/SCP protocol and Qualcomm QC4.0+ protocol. It is designed for USB power delivery AC/DC off-line adapter or charger application.

OB2613X works as Source and communicates with Sink on the CC wire using the USB PD3.0 protocol. The mixed-signal front end on the CC pins advertises default (500 mA), 1.5 A or 3 A for Type-C power sources, detects a plug event and determines the USB Type-C cable orientation, and autonomously negotiates USB PD contracts by adhering to the specified bi-phase marked coding (BMC) and physical layer (PHY) protocol. OB2613X can also monitor USB DP/DN data line voltage or DN data line transmission that supports Qualcomm QC3.0 and Huawei fast charging FCP, and automatically adjusts output voltage and output current.
