FT3103 - Fortior

FT3103 Three Phase Sensorless BLDC Motor Controller

The FT3103 is a Three Phase sensorless BLDC Motor controller with built-in driver. Due to its adaptive features and wide power-supply range capabilities, FT3103 is intended to cover a wide range of motor characteristics, while requiring minimal tuning from the user. Two drive modes are provided, namely SBLDC (quasi-sine-wave) modulation or BLDC (120°). Speed.

Features

and wide power-supply range capabilities, FT3103 is intended to cover a wide range of motor characteristics, while requiring minimal tuning from the user. Two drive modes are provided, namely SBLDC (quasi-sine-wave) modulation or BLDC (120°). Speed can be controlled either by setting the closed speed reference directly or through the adjustment of PWM duty cycle linearly proportional to the output speed. Speed indicator is provided through a Frequency Generator output (FG×3), generating digital pulse with its frequency proportional to the speed of the motor. Protection functions of FT3103 are .
