单极 2 相步进电机驱动器

概览

STK672-632AN-E 是一款混合集成电路,使用带有 PWM 电流控制的 2 相步进电机驱动器。它包括内置的控制器,基于单极恒定电流 PWM 系统。STK672-632AN-E 提供了内置的 4 相分布步进电机控制器,支持应用简化和标准化。它支持五种励磁方法: 2 相和 1-2 相励磁,可提供步进电机除以 1/2 步进单位的基本步进角度控制。它还通过时钟信号即可实现电机速度控制。此混合集成电路的使用使得设计人员能够实施提供高电机转矩、低振动水平、低噪声、快速响应和高能效驱动的系统。另外,STK672-632AN-E 具有针对过电流、过热和电机端子开路的各种保护功能,STK672-630AN-E 采用连接散热片的带孔封装。
