L6227N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L6227N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)的簡單開環(huán)速度控制到基于步進(jìn)電機(jī)的高級閉環(huán)運(yùn)動(dòng)控制。

DESCRIPTION

The L6227 is a DMOS Dual Full Bridge designed for motor control applications, realized in MultiPower BCD technology, which combines isolated DMOS Power Transistors with CMOS and bipolar circuits on the same chip. The device also includes two inde pendent constant off time PWM Current Controllers that performs the chopping regulation. Available in Power DIP24 (20+2+2), PowerSO36 and SO24 (20+2+2) packages, the L6227 features a non-dissipative overcurrent protection on the high side Power MOSFETs and thermal shutdown.
