LC898111AXB集成电路（IC）的电机驱动器控制器规格书PDF中文资料

LC898111AXB属于集成电路（IC）的电机驱动器控制器。由安森美半导体公司制造生产的LC898111AXB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

The LC898111AXA and the LC898111AXB are image stabilization system control LSIs for smartphone camera modules.

The LSIs have built-in digital signal processing circuits, such as a 2ch saturation H-Bridge Driver and a Flexible Filter circuit, and control VCM type actuators.

The LC898111AXA and the LC898111AXB are identical LSIs except for the dimensions, i.e. XA has WLP thickness, max. 0.33 mm without back coat (B/C) and XB has WLP thickness, max. 0.69 mm with B/C.
