MCP8063-E/MD 3-phase motor driver, 2 ... 14V, 1.5A, DFN-8

3-Phase Brushless Sinusoidal Sensorless Motor Driver

Description: 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 compact packaging and minimum bill-of-material (BOM), it is best suited for fan applications that require high efficiency and low acoustic noise. Frequency generator output is also included, enabling for precision speed control in closed-loop applications. The MCP8063 driver includes a lockup 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. Automotive AEC-Q100 Qualified, PPAP Available Upon Request.
