L6229Q屬于集成電路（IC）的電機(jī)驅(qū)動(dòng)器控制器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的L6229Q電機(jī)驅(qū)動(dòng)器，控制器產(chǎn)品屬于電機(jī)驅(qū)動(dòng)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(jī)或相關(guān)機(jī)電執(zhí)行器的電源。所實(shí)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(jī)的簡(jiǎn)單開環(huán)速度控制到基于步進(jìn)電機(jī)的高級(jí)閉環(huán)運(yùn)動(dòng)控制。

描述 Description

The L6229Q is a DMOS fully integrated threephase motor driver with overcurrent protection.

Realized in BCDmultipower technology, the device combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip.

The device includes all the circuitry needed to drive a three-phase BLDC motor including: a three-phase DMOS bridge, a constant off time PWM current controller and the decoding logic for single ended hall sensors that generates the required sequence for the power stage.
