概览

STK672-440BN-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。它包括内置的微步控制器，基于单极恒定电流 PWM 系统。STK672-440BN-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，1-2 相，W1-2 相，2W1-2 相和 4W1-2 相励磁，可提供步进电机除以 1/16 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，STK672-440BN-E 还具有多种针对过电流、过热和电机端子开路的保护功能。还推出了小封装型 STK672-442BN-E，没有联接散热的孔。
