Freedom评估板采用MC34933双通道H桥驱动器,可驱动一个步进电机或两个有刷直流电机。
FRDM-34933EP-EVB设计巧妙,能轻松地安装到FRDM-KL25Z上
MC34933采用我们专有的SMOS8 Bi CMOS工艺,是一款低功耗器件,工作电压范围为2.0 V至7.0 V,用于电机驱动时的最大静态电流为100uA,用于控制逻辑供电时的最大静态电流为400uA。MC34933采用VCC检测电路,检测逻辑电源开关何时处于关闭状态,最大电流为1uA,可延长电池使用时间。MC34933还为H桥驱动器提供热保护电路,可避免对IC内部功率MOSFET电路的损害,内置死区时间控制可预防直通电流。MC34933能够驱动高达1.0 A的负载(峰值1.4 A)。
