CXMD3296是一款用于数码相机等的4+2通道H桥电机驱动芯片。它有四个全摆幅/恒压驱动器和一个全摆幅/恒流驱动器。CXMD3296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4+1全回转驱动器，通过带制动功能的串行控制切换
内置1个用于快门或光圈的恒流驱动器
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）
内置热停堆（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：CH13/23（用于STM-B）设置5CH组合控制模式
内置独占控制方式：CH35（DCM），设置6CH组合控制方式
所有电源系统（VCC、VM12、VM345）都可以设置独立的电源
串行控制设置对应的省电模式
PI（光电干扰驱动器）3通道内置
PR比较器2通道内置。

产品概述 返回TOP
CXMD3296 is a 4+2 channel H-Bridge motor drivers IC for the digital camera and so on. It has four full-swing/ constant voltage drivers and one full-swing/constant current drivers. CXMD3296 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 4+1 full-swing 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 (for STM-B) the combination control mode of 5CH is set
Built in exclusive control mode: CH35 (for DCM), the combination control mode of 6CH is set
All power supply systems (VCC, VM12, VM345) can be set up with an independent power supply
Power save mode corresponds by serial control setup
PI (photo interrapter drive) 3 channel built-in
PR Comparator 2 channel built-in.
Small 28QFN (4×4mm) is adopted.
