MC3479P集成电路（IC）的电机驱动器控制器规格书PDF中文资料

MC3479P属于集成电路（IC）的电机驱动器控制器。由安森美半导体公司制造生产的MC3479P电机驱动器，控制器产品属于电机驱动器和控制器电源管理集成电路 (PMIC) 系列，可用于控制或操作从某电源施加到电机或相关机电执行器的电源。所实现的具体功能和特性集根据预期负载和预期应用的特性有很大差异，范围从用于有刷电机的简单开环速度控制到基于步进电机的高级闭环运动控制。

The MC3479 is designed to drive a two–phase stepper motor in the bipolar mode. The circuit consists of four input sections, a logic decoding/sequencing section, two driver–stages for the motor coils, and an output to indicate the Phase Adrive state.
