The MCP8063 is a highly integrated, cost-effective, automotive AEC-Q100-qualified motor driver from Microchip that has been designed to provide improved levels of performance in a small, 8-pin, 4×4 mm DFN package. It is said to be the first device 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 helps to reduce 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. In addition, the MCP8063 includes safety features such as thermal shutdown, over-current limiting and lock-up protection.
Design engineers of a broad range of motor applications in markets such as the automotive, IT, industrial and home-appliances 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 look to solve these problems cost-effectively, while providing a wide operating temperature range of -40 to +125-degrees Celsius. It also supports the sensorless driving of BLDC motors, which eliminates the cost and space of a Hall sensor.
The compact MCP8063 is a high-performance motor driver which offers high current and a wide temperature range to provide a complete single-chip solution for a wide variety of three-phase, brushless DC applications.
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 has also announced the MCP8063 12V 3-Phase BLDC Sensorless Fan Controller Demo Kit (ADM00575). This comes with a user-friendly configuration GUI.
