Bangkok — Microchip Technology Inc. has launched a highly integrated and compact motor driver in an 8-pin, 4×4-mm DFN package. The MCP8063 is touted as the industry’s first 1.5-A, three-phase brushless DC, sinusoidal motor driver that is automotive AEC-Q100 qualified.
Targeting a variety of three-phase brushless DC motor and fan applications, the integration of the MCP8063 helps reduce cost and printed-circuit-board area, while the high sinusoidal-drive performance provides high efficiency, low acoustic noise and low mechanical vibration for energy savings and quiet operation, said Microchip. The motor driver also includes safety features such as thermal shutdown, over-current limiting and lock-up protection.
The MCP8063 is well suited for a broad range of motor applications in markets such as automotive, IT, industrial and home-appliance sectors that are faced with increasing regulatory and consumer demands for continued reductions in cost, space, noise and power consumption as well as better performance and safety, said Microchip. The device supports the sensorless driving of BLDC motors, which eliminates the cost and space of a Hall sensor, and offers a wide operating temperature range of -40 to +125-degrees C.
The MCP8063 motor driver works standalone or in conjunction with Microchip’s portfolio of PIC microcontrollers and dsPIC digital signal controllers. This offers a high degree of flexibility for everything from simple voltage control to closed-loop motor speed control using high-performance algorithms, such as sinusoidal sensorless drive, said Microchip.
Microchip also offers the MCP8063 12V 3-phase BLDC Sensorless Fan Controller Demo Kit (part # ADM00575). The tool comes with a user-friendly configuration GUI. Microchip also supports its motor control and driver portfolios with a full range of development solutions, including firmware, algorithms, application notes, development tools, evaluation boards, and reference designs.
Availability: The MCP8063 motor driver is available for samples and volume production in 5,000-unit quantities.
