MICROCHIP MCP8063-E/MD

The MCP8063-E/MD is a highly integrated 3-phase full-wave Sinusoidal Sensorless Driver for brushless motors. It features a 180° sinusoidal drive, high torque output and silent drive. Its integrated features and the wide power supply range make it an ideal candidate for a broad range of motor characteristics, requiring no external tuning. Speed control can be achieved through either power supply modulation or pulse-width modulation. It is optimized for fan applications that require high efficiency and low acoustic noise. Frequency generator output enables precision speed control in closed-loop applications. The MCP8063 driver 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 restart when the lock condition is removed. Features such as motor overcurrent limitation and thermal shutdown protection improve motor system reliability without additional efforts from design engineers.
