MCP8063T-E/MD

The MCP8063 device is a highly integrated 3-phase, full-wave 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 (2V to 14V) make the MCP8063 an ideal candidate for a broad range of motor characteristics, requiring no external tuning. Speed control can be achieved through either power supply modulation (PSM) or pulse-width modulation (PWM). Due to the compact packaging and minimum bill of materials (power transistors integrated, no Hall sensor, no external tuning), the MCP8063 is optimized for fan applications that require high efficiency and low acoustic noise at competitive costs. 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. The MCP8063 is available in a compact thermally-enhanced 8-lead 4 mm x 4 mm DFN package with exposed pad.
