Product Overview

FA1611 is a fully integrated IC with built-in MOS and Hall-based sensor for single-phase BLDC motor driver applications. It supports soft-switching square-wave control mode, and features with low noise. Motor control parameters, such as soft-switching slope, lead angle, etc., can be flexibly configured via GUI to achieve required efficiency and reduce noise, in order to meet different application requirements. Moreover, the chip supports 4-segment speed control curve, protection restart configurations and FG/RD output to fulfill different input and output requirements.
