CXMD32103是用于数码相机等的8i+1通道H桥电机驱动芯片。它有八个全摆/恒压驱动器和一个全摆/恒流/恒压驱动器。CXMD32103可以在串行控制模式或部分外部控制模式下操作。在部分外部控制模式下运行时，每个通道的模式由初始串行控制设置固定。在串行控制模式下工作时，可以通过串行控制设置每个驱动器的模式。串行接口（I2C），以高达400 KHz的时钟速率工作。
内置4个全摆幅/恒压驱动器，用于模拟微型浸泡电机。（STM OIS公司）
内置1个快门或光圈的全摆幅/恒流驱动器
·内置3+1全摆幅/恒压驱动器，通过带制动功能的串行控制进行切换。
·低导通电阻（1.2Ω，上部和底部导通电阻之和）
输出电流：每个通道的IB OUTB<=0.8A（最大值）
内置热关机（TSD，150°C）
·CH1/2对应于2-2相或1-2相的STM控制

产品概述 返回TOP
CXMD32103 is a 8i+1-channel H-Bridge motor drivers IC for the digital camera and so on. It has eight full-swing/constant voltage drivers and one fullswing/constant current/constant voltage drivers. CXMD32103 can be operated in serial control mode or partial exterior control mode. When operating in partial exterior control mode, the mode of each CH is fixed by initial serial control setting. When operating in serial control mode, the mode of each driver can be setting by serial control. The serial interface (I2C) that operates at clock rates up to 400 KHz.
