AMT49400 Integrated Sensorless FOC BLDC Driver

Allegro MicroSystems

Allegro MicroSystems Motor Drivers offer robustness and safety, delivering superior performance in harsh, high voltage environments. These durable drivers enable motors to run more quietly, efficiently, and reliably. The embedded motion control algorithms simplify designs while improving motor performance and time-to-market. The Allegro MicroSystems Motor Driver portfolio includes brushless DC drivers, brush DC drivers, and stepper drivers for automotive, industrial, and consumer applications.

The AMT49400 is an advanced 3-phase, sensorless, brushless DC (BLDC) motor driver with integrated power MOSFETs.A minimal application circuit can be achieved with only two external components due to device’s high level of integration, which includes control algorithm, analog circuit, and power stage.A field-oriented control (FOC) algorithm is fully integrated to achieve the best efficiency and acoustic noise performance. EEPROM programmability is included to optimize motor startup performance.The motor speed is controlled by applying a duty cycle command to the PWM input. A simple I2C interface is provided for setting motor-rated voltage, rated current, rated speed, resistance, and startup profiles. The I2C interface is also used for on/off control, speed control, and speed readback.The AMT49400 is available in a 10-lead SOIC with exposed pad, (suffix LK)
