MCP8063: Cost Effective 1.5A Three-Phase Brushless DC, Sinusoidal Motor Driver
The MCP8063 is a highly integrated sinusoidal sensorless driver for brushless DC motors. It features 180° sinusoidal drive for high torque output and silent operation. It is intended to cover a wide range of motor characteristics, while requiring no external tuning from the user. Speed control can be achieved through either power supply or pulse-width-modulation (using the PWM digital input pin). The MCP8063 includes a lock-up protection mode, which turns-off the output current when the motor is under lock condition, and an automatic recovery that enables the fan to run when the lock condition is removed.
