LC898302AXA集成电路（IC）的电机驱动器控制器规格书PDF中文资料

LC898302AXA属于集成电路（IC）的电机驱动器控制器。由安森美半导体制造生产的LC898302AXA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。

Overview

LC898302AXA is a LRA (Linear Resonant Actuator) & ERM

(Eccentric Rotating Mass) Driver IC dedicated to haptic feedback

actuator and vibrator employed in mobile equipment. Due to the

product superior technology, the drive frequency is automatically

adjusted to the resonance frequency of the linear vibrator without the

use of other external parts. As a result of this very effective drive, the

vibration is as powerful as possible using very limited amount of

energy compared to classical solutions

The drive and brake are fully configurable through the PWM−IF

setting.

Finally, the original driving waveform allows you to reduce power

consumption and it is useful to maintain battery lifetime.
