Highly Integrated Secondary-Side Adaptive USB Type-C Charging Controller with USB-PD

The FAN63901JMPX is a highly integrated, secondary-side power adapter 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 3.3V to 21V and current limits from 1A to 3A to meet a wide range of applications and power levels. To minimize BOM count, the FAN63901JMPX includes 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 adapter, 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.
