MCT8315A High Speed Sensorless Trapezoidal Control Integrated FET BLDC Driver
1 Features
• Three-phase BLDC motor driver with integrated sensorless motor control algorithm
– Code-free high speed Trapezoidal Control – Supports up to 3 kHz (electrical frequency) – Very fast start-up time (< 50 ms) – Fast Deceleration (< 150 ms) – Supports 120° or 150° modulation to improve
acoustic performance – Windmilling support through forward
resynchronization and reverse drive – Analog, PWM, freq. or I2C based speed input – Active Demagnetization to reduce power losses – Configurable motor start-up and stop options – Closed speed/power loop options – Anti-voltage surge (AVS) protection prevents
DC bus voltage spike during motor deceleration • 4.
