L6229集成電路（IC）的電機驅動器控制器規(guī)格書PDF中文資料

L6229屬于集成電路（IC）的電機驅動器控制器。由意法半導體集團制造生產(chǎn)的L6229電機驅動器，控制器產(chǎn)品屬于電機驅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)預期負載和預期應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。

DESCRIPTION

The L6229 is a DMOS Fully Integrated Three-Phase Motor Driver with Overcurrent Protection.

Realized in MultiPower-BCD 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.
