DMOS Microstepping Driver with Translator

Description The A3987 is a complete microstepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full, half, quarter, and sixteenth step modes, with output drive capability of 50 V and ±1.5 A. The A3987 includes a fixed off-time cur

带转换器的 DMOS 微步驱动器

A3987 是一款完全的微步电动机驱动器，带有内置转换器，易于操作。该产品可在完整、1/2、1/4 及 1/16 步进模式时操作双极步进电动机，输出驱动容量为 50 伏特及 1.5 安培。A3987 包括一个固定停机时间电流稳压器，该稳压器可在慢或混合衰减模式下工作。\n\n转换器是 A3987 易于实施的关键。只要在“步进”输入中输入一个脉冲，即可驱动电动机产生一个微步。该程序中没有相位顺序表、高频率控制行或复杂的界面。A3987 界面对于复杂的微处理器不可用或过载时的应用情况下是理想的器件。\n\nA3987 斩波控制可自动选择电流衰减模式（慢或混合）。当出现一个“步进”信号时，该转换器会 • 低 RDS(on) 输出 \n• 加载短路保护 \n• 混合与慢电流衰减模式 \n• 内部欠压锁定 (UVLO) 及过热关机电路 \n• 交叉电流保护 \n;
