Microchip MCP8063三相正弦无传感器无刷马达驱动方案
Microchip公司的MCP8063是高度集成的三相正弦无传感器无刷马达驱动器,具有180°正弦驱动,高扭矩输出和静音驱动,工作电压2V-14V,速度控制可通过脉宽调制(PWM)或电源调制(PSM)取得.内置了频率发生器,锁住保护和自动重起电路,过流保护,过压保护和热关断保护,主要用在安静笔记本CPU/GPU冷却风扇,12V三相BLDC马达和通风设备系统.本文介绍了MCP8063主要特性,框图,风扇马达驱动应用电路以及12V三相BLDC无传感器风扇控制器演示板主要特性,电路图,材料清单和PCB设计图.
The MCP8063 device is a highly integrated 3-phase,full-wave sensorless driver for brushless motors. Itfeatures a 180° sinusoidal drive, high torque output,and silent drive. Its integrated features and the widepower supply range (2V to 14V) make the MCP8063 anideal candidate for a broad range of motorcharacteristics, requiring no external tuning. Speedcontrol can be achieved through either power supplymodulation (PSM) or pulse-width modulation (PWM).
