MC33033屬于集成電路（IC）的電機驅(qū)動器控制器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC33033電機驅(qū)動器，控制器產(chǎn)品屬于電機驅(qū)動器和控制器電源管理集成電路 (PMIC) 系列，可用于控制或操作從某電源施加到電機或相關(guān)機電執(zhí)行器的電源。所實現(xiàn)的具體功能和特性集根據(jù)預(yù)期負(fù)載和預(yù)期應(yīng)用的特性有很大差異，范圍從用于有刷電機的簡單開環(huán)速度控制到基于步進電機的高級閉環(huán)運動控制。

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.
