This BLDC motor controller, based on the Allegro A89301 chip, enables sensorless control over a wide voltage range from 5.5 V to 48 V and phase current up to 11 A without additional cooling. It supports four control modes: analog voltage, PWM signal, pulse frequency, and via an I²C interface with the ability to configure parameters and save settings to EEPROM. The Field-Oriented Control (FOC) algorithm ensures quiet and efficient operation, while built-in protection protects the system against short circuits, reverse polarity, and undervoltage.
