Cost-Effective MCP8063 is World’s First 1.5 Ampere, Three-Phase Brushless DC,
Sinusoidal Motor Driver in a 4×4 mm Package With the AEC-Q100 Quality certification.
CHANDLER, Ariz., April 8, 2014 [NASDAQ: MCHP] — Microchip Technology Inc., a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today announced the MCP8063—a highly integrated, cost-effective, automotive AEC-Q100-qualified motor driver that delivers superior performance 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.
