1.5A automotive BLDC motor driver in 4 x 4 mm outline

April 09, 2014 // By Graham Prophet
Microchip’s latest motor drive IC is automotive AEC-Q100 qualified; the MCP8063 is a 1.5A, three-phase brushless DC, sinusoidal motor driver in a 4 x 4 mm package with AEC-Q100 quality certification.

Delivering 1.5A peak phase current for the 180-degree sinusoidal drive of a variety of three-phase brushless DC motor and fan applications, its high level of integration cuts 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.

MCP8063 includes safety features such as thermal shutdown, over-current limiting and lock-up protection. It operates over -40 to +125C and 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 at attractive price points.

The MCP8063 motor driver works stand-alone or in conjunction with Microchip’s PIC microcontrollers and dsPIC digital signal controllers, for designs from simple voltage control to closed-loop motor speed control using high-performance algorithms, such as sinusoidal sensorless drive.

Microchip has the MCP8063 12V 3-Phase BLDC Sensorless Fan Controller Demo Kit (ADM00575), at $49.99, which comes with a configuration GUI.
