电机控制集成电路的选用——第七讲 步进电机驱动电路UC3770的选用

Selection and Operation of Integrated Circuit for Motor Control——Lecture Seven·Selection and Operation of controlling Step motor IC UC3770

U C3770 A/B是一种高性能全桥驱动芯片 ,可提供更高的工作电流和更低的饱和电压。利用数片UC3770 A /B以及少量的外围元件可构成完整的步进电动机驱动系统 ,其驱动信号可由微处理器及逻辑电路提供。

The UC3770A/B is high-performance full bridge drivers. It can offer higher current and lower saturation voltage than UC3717.Two UC3770A/B and a few external components form a complete control and drive unit for LS-TTL or micro-processor controlled stepper motor systems.
