FUSB15101中文資料安森美半導體數據手冊PDF規(guī)格書

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

regulator.

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.
