摘　　要：A3977是Allegro Microsystems公司生产的两相微步距步进电机驱动器,片内所含脉冲分配器使每输入一个脉冲,电机就走一步,不需要相序表、高频控制线或复杂的程序接口。最后还介绍了A3977的典型应用电路。A3977 is a complete microstepping motor driver integrated circuit with integrated step and direction translator,produced by Allegro Microsystems,Inc.By simply inputting one pulse on the step input, the motor will take one step.there are no phase-sequence tables, high-frequency control lines,or complex interfases to program.The model applicated hardware circuit of A3977 is stated in paper.
