CXMD32101数码相机5+1通道H桥电机驱动芯片微步进驱动器两个全摆恒压驱动器一个全摆恒流驱动器2-2相步进驱动到最高1024分辨率微步进光断续器驱动3通道内置

CXMD32101是一款用于数码相机等的5+1通道H桥电机驱动芯片。它有一个微步进驱动器，两个全摆/恒压驱动器和一个全摆/恒流驱动器。CXMD32101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。

内置一个微步进驱动模式可以从2-2相步进驱动到最高1024分辨率微步进。
内置2个全摆幅/恒压驱动器，通过带制动功能的串行控制进行切换
内置1个恒流驱动器，用于快门或光圈
内置CH3 DCM FLL功能
“低导通电阻（1.2Ω，上下侧导通电阻之和）”，输出电流：各通道输出<=0.8A（最大值）
内置热关机（TSD，150°C）
·所有电源系统（VCC、VM12、VM3、VM45）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。

        CXMD32101 is a 5+1-channel H-Bridge motor drivers IC for the digital camera and so on. It has one micro-stepping driver, two full-swing/constant voltage drivers and one full-swing/constant current drivers. CXMD32101 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.
