CXMD3289用于数码相机等的6+1通道H桥电机驱动芯片两个微步进驱动器两个全摆幅恒压恒流驱动器串行控制模式或部分外部控制模式下操作两个微步驱动模式从2-2相步进电机驱动到最大256分辨率微步

CXMD3289是一款用于数码相机等的6+1通道H桥电机驱动芯片。它有两个微步进驱动器，两个全摆幅/恒压/恒流驱动器。CXMD3289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。

·内置两个微步驱动模式，从2-2相步进电机驱动到最大256分辨率微步。
内置2个全摆幅/恒压/恒流驱动器，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：每个通道的输出电流<=0.8A（最大值）
内置热关机（TSD，150°C）
·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。
采用小40TQFN（5×5mm）
·内置POR（上电复位）。

      CXMD3289 is a 6+1-channel H-Bridge motor drivers IC for the digital camera and so on. It has two micro-stepping drivers, two full-swing/constant voltage/constant current drivers. CXMD3289 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.

„Build-in two micro-steps drive mode is possible from 2-2 phase stepper drive to maximum 256 resolution micro-steps. 

„ Built in 2 full-swing/constant voltage/constant current drivers switched by serial control with brake function 

„ Low on-resistance (1.2Ω, sum of on-resistance of upside and bottom side) 

„ Output current：IOUT<=0.8A(max.) for each channel 

„ Build-in thermal shutdown (TSD, 150°C) 

„ All power supply systems (VCC, VM12, VM34, VM5, VM6) can be set up with an independent power supply 

„ Power save mode corresponds by serial control setup 

„ PI (photo interrupter drive) 3 channel built-in. 

„ Small 40TQFN (5×5mm) is adopted 

„ Build-in POR (power on reset).
