  • Commodity Description
德州仪器 DRV8308 无刷直流电机控制器是一款三相半桥前置驱动器,此驱动器在由单电源供电的情况下能够将高达 130mA 的电流驱动进 6 个 N 类型 MOSFET 中。针对传感式三相无刷直流电机,此前置驱动器包括可配置数字速度环路、速度控制和换相模式,用以优化电机性能。经适当调节,DRV8308 器件能够以少于 0.1% 的周期抖动和快速转矩补偿来驱动电机。借助可编程增益和环路滤波器,集成数字速度环路可以使电机在负载变化时保持速度。可调转换率也能够降低开关噪声,并且改进电磁兼容性 (EMC)。DRV8308 器件还借助延迟调节功能支持 120° 和 180° 换相模式,以增加功效。为实现高性能系统,使用了正弦(180°)换相模式,最大限度地减少了可闻噪声和转矩纹波。一旦通过三个霍尔传感器相位至仅仅一个霍尔传感器的切换达到恒定速度,由非理想霍尔元件放置方式和匹配导致的抖动可被消除。 了解更多
