AEC-Q100 Motor Driver provides High Performance and 1.5A Peak Current

Microchip Technology Inc. today announced the MCP8063—a highly-integrated, cost-effective, automotive AEC-Q100-qualified motor driver in a small, 8-pin, 4×4 mm DFN package. It is also the world’s first to combine all of those features with 1.5A peak phase current for the 180-degree sinusoidal drive of a variety of three-phase brushless dc motor and fan applications. This integration reduces cost and PCB area, and the high sinusoidal-drive performance provides high efficiency, low acoustic noise and low mechanical vibration for energy savings and quiet operation. Additionally, the MCP8063 includes safety features such as thermal shutdown, over-current limiting and lock-up protection.

The designers of a broad range of motor applications in markets such as the automotive, IT, industrial and home-appliance sectors are faced with increasing regulatory and consumer demands for continued reductions in cost, space, noise and power consumption; with better performance and safety. The integrated features of the MCP8063 motor driver solve these problems cost effectively, while providing a wide operating temperature range of -40 to +125 degrees Celsius. Additionally, it supports the sensorless driving of BLDC motors, which eliminates the cost and space of a Hall sensor.

"Customers requested a compact, high-performance motor driver with high current and a wide temperature range, while adhering to the AEC-Q100 quality standard," said Bryan J. Liddiard, marketing vice president of Microchip's Analog and Interface Products Division. "Our new MCP8063 delivers on that request, providing a complete single-chip solution for a wide variety of three-phase, brushless DC applications at attractive price points."

The MCP8063 motor driver works stand-alone or in conjunction with Microchip's large 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.

To enable development with the new MCP8063 motor driver, Microchip also announced the MCP8063 12V 3-Phase BLDC Sensorless Fan Controller Demo Kit (part # ADM00575), which is available today for $49.99 each. Additionally, this 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. The MCP8063 motor driver is available today for samples and volume production, at the attractive price point of $1.12 each in 5,000-unit quantities.
