Highly Integrated Secondary-
Side Adaptive USB Type-C
Charging Controller with
USB-PD with SR Embedded
FAN6390MPX
www.onsemi.com
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.
