L6460TR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L6460TR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。

Description

The L6460 is optimized to control and drive multimotor system providing a unique level of integration in term of control, power and auxiliary features. Thanks to the high configurability L6460 can be customized to drive different motor architectures and to optimize the number of embedded features, such as the voltage regulators, the high precision A/D converter, the operational amplifier and the voltage comparators. The possibility to drive simultaneously stepper and DC motor makes L6460 the ideal solution for all the application featuring multi motors.
