MC34931: MC34931/S H桥，有刷直流电机驱动器，5-36V，5A，11kHz/20kHz

恩智浦MC34931是一个单片式高散热效率的36V/5A H桥DC电机驱动器。

特性

最佳散热性：eSOIC封装的热抗阻降低了2倍多，可节约电路板空间并简化设计
自动热关断功能：温度调节和峰值电流限制功能可确保连续运行及高可用性
实时负载电流监控：用于电机控制或负载保护的模拟回馈电流镜功能
简洁的设计：集成式H桥，带电荷泵、控制、保护和4个MOSFET
高性能：120 mΩ典型导通电阻
5.0 V至36 V连续工作，42 V瞬态电压
高达5A的工作电流，适用于广泛的应用。
兼容3和5V TTL/CMOS
状态标志输出报告欠压、过流和过热故障情况
输出短路保护(短接至VPWR或GND)
睡眠模式电流消耗 < 20 μA
