AH289-PL-B集成电路（IC）的电机驱动器控制器规格书PDF中文资料

AH289-PL-B属于集成电路（IC）的电机驱动器控制器。由美台半导体制造生产的AH289-PL-B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。

General Description

AH289 is a monolithic fan motor controller with Hall sensor’s capability. It contains two complementary open-drain transistors for motors coil driving, an automatic lock current shutdown, and recovery protection. In addition, the Rotor-State Detection (RD) output is for Rotor-State Detection.

Rotor-lock shutdown detection circuit turns off the output driver when the rotor is blocked to avoid coil overheat. Then, the automatic recovery circuit will restart the motor. These protected actions are repeated and periodic during the blocked period. Until the blocking is removed, the motor recovers and runs normally.
