CXMD3297是一款用于数码相机等的4+2通道H桥电机驱动芯片。它有三个全摆幅/恒压驱动器和一个全摆幅/恒流驱动器。CXMD3297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3个全回转/恒压驱动器，通过带制动功能的串行控制切换。
内置1个恒流驱动器，用于快门或光圈。
·低导通电阻（1.2Ω，上部和底部导通电阻之和）。
·输出电流：每个通道输出<=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。
·内置独占控制模式：CH13/23Æ设置5CH组合控制模式。
·内置独占控制模式：CH3/4（用于DCM）设置6CH的组合控制模式。
·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
CXMD3297 is a 4+2-channel H-Bridge motor drivers IC for the digital camera and so on. It has three full-swing/constant voltage drivers and one full-swing/constant current drivers. CXMD3297 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.
产品特点 返回TOP
„ Built in 3 full-swing/constant voltage drivers switched by serial control with brake function.
„ Built in 1 constant current drivers for shutter or IRIS.
„ 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).
„ CH1/2 corresponds to STM control of 2-2 phase or 1-2 phase.
„ Built in exclusive control mode: CH13/23 Æ the combination control mode of 5CH is set.
„ Built in exclusive control mode: CH3/4(for DCM) Æ the combination control mode of 6CH is set.
„ Power save mode corresponds by serial control setup.
„ PI (photo interrupter drive) 3 channel built-in.
„ Small 20TQFN (3×3mm) is adopted.
