Overview: Highly Integrated SecondarySide Adaptive USB Type-C Charging Controller with USB-PD with SR Embedded FAN6390MPX
The FAN6390MPX is a highly integrated, secondary−side power adaptor controller supporting USB Type−C and USB Power Delivery 2.0/3.0. It includes a fully autonomous USB PD state machine which is fully compliant with the latest USB PD 3.0 specification, minimizing design time and cost. Support for the latest Programmable Power Supply (PPS) rules allows for control of voltages from 3.3 V to 21 V and current limits from 1 A to 3 A to meet a wide range of applications and power levels.
To minimize BOM count, the FAN6390MPX includes internal synchronous rectifier control, an NMOS gate driver for VBUS load switch control, as well as Constant Voltage (CV) and Constant Current (CC) control blocks with adjustable internal references. To ensure proper operation of the adaptor, various protections are integrated into the controller including output over−voltage protection, under− voltage protection, external over−temperature protection via NTC, internal over−temperature protection, CC over voltage protection and Cable Fault Protection.
