The FUSB15101 is a highly integrated USB Power Delivery (PD)
power source controller that can control the opto−coupler in the
secondary side of an AC−DC adapter or a DC−DC port power
The FUSB15101 enables a complete solution for USB power
sources through optimized hardware peripherals and complete
open−source embedded firmware all in a compact solution.
It integrates a highly efficient Arm® Cortex®−M0+ processor with
custom designed peripherals to seamlessly support USB PD 3.1 source
applications. The FUSB15101 supports the PPS specification in USB
PD, with a minimum of 3.3 V and a maximum of 21 V output voltage
control. It includes Constant Voltage (CV) and Constant Current Limit
(CL) control blocks, various protection mechanisms and high voltage
tolerance on connector pins.
