CXMD3295是一款用于数码相机等的6通道H桥电机驱动芯片。它有五个全摆/恒压驱动器和两个全摆/恒流驱动器。CXMD3295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。
内置5个全摆/恒压驱动器，通过带制动功能的串行控制切换
内置2个恒流驱动器，用于快门或光圈
“低导通电阻（1.2Ω，上侧和下侧导通电阻之和）”，输出电流：Iout<=0.8A（最大值）
内置热关机（TSD，150°C）
·内置CC模式弱激励
·CH1/2、CH3/4和CH5/6对应于2-2相或1-2相的STM控制
·所有电源系统（VCC、VM12、VM34、VM5、VM6）都可以设置独立的电源
·节电模式对应于串行控制设置
·PI（光断续器驱动）3通道内置。

产品概述 返回TOP
CXMD3295 is a 6-channel H-Bridge motor drivers IC for the digital camera and so on. It has five full-swing/constant voltage drivers and two full-swing/constant current drivers. CXMD3295 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.
