MC33033DW集成电路（IC）的电机驱动器控制器规格书PDF中文资料

MC33033DW属于集成电路（IC）的电机驱动器控制器。由安森美半导体制造生产的MC33033DW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。

Brushless DC Motor Controller

The MC33033 is a high performance second generation, limited feature, monolithic brushless dc motor controller which has evolved from ON Semiconductor’s full featured MC33034 and MC33035 controllers. It contains all of the active functions required for the implementation of open loop, three or four phase motor control. The device consists of a rotor position decoder for proper commutation sequencing, temperature compensated reference capable of supplying sensor power, frequency programmable sawtooth oscillator, fully accessible error amplifier, pulse width modulator comparator, three open collector top drivers, and three high current totem pole bottom drivers ideally suited for driving power MOSFETs. Unlike its predecessors, it does not feature separate drive circuit supply and ground pins, brake input, or fault output signal.
