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 pulse distributor,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 wire,or complex interfaces for program.The model applicated hardware circuit of A3977 is stated in this paper.
