L6234集成电路（IC）的电机驱动器控制器规格书PDF中文资料

L6234属于集成电路（IC）的电机驱动器控制器。由意法半导体集团制造生产的L6234电机驱动器，控制器产品属于电机驱动器和控制器电源管理集成电路 (PMIC) 系列，可用于控制或操作从某电源施加到电机或相关机电执行器的电源。所实现的具体功能和特性集根据预期负载和预期应用的特性有很大差异，范围从用于有刷电机的简单开环速度控制到基于步进电机的高级闭环运动控制。

DESCRIPTION

The L6234 is a triple half bridge to drive a brushless motor.

It is realized in Multipower BCD technology which combines isolated DMOS power transistors with CMOS and Bipolar circuits on the same chip.

By using mixed technology it has been possible to optimize the logic circuitry and the power stage to achieve the best possible performance.
