CXMD3286 CXMD3287 CXMD3288反共模接通电路N通道和P通道功率mosfet的片上H桥驱动电路驱动无刷直流电机或步进电机绕组连续输出电流2.6A电刷直流电机驱动解决方案

CXMD3286 CXMD3287 CXMD3288为电池驱动的玩具、低压或电池驱动的运动控制应用提供了集成的电刷直流电机驱动解决方案。该电路集成了N通道和P通道功率mosfet的片上H桥驱动电路，适用于驱动无刷直流电机或步进电机绕组。工作电压范围较宽（2V～12.0V），最大连续输出电流可达2.6A，最大峰值输出电流可达4A，VCC与VDD串联供电，VCC为逻辑控制电源，VDD为电源。CXMD3286 CXMD3287 CXMD3288具有片内温度保护功能。当驱动电路的负载电流远大于电路的最大持续电流时，电路的结温会迅速升高。一旦超过设定值（150摄氏度），内部电路将立即关闭输出电源管，切断负载电流，避免温度持续上升造成塑料包装冒烟、起火等安全隐患。内置温度滞后电路，以确保电路恢复到安全温度之前，允许电路重新控制。CXMD3286 CXMD3287 CXMD3288设置了单独的电流采样输出引脚，采样输出电流采样比为1000:1。输出采样电流用于单片机分析或控制外部电路来控制输出电流。

   CXMD3286 CXMD3287 CXMD3288 provides an integrated brush DC motor drive solution for battery-powered toys, low-voltage or battery-powered motion control applications. The circuit integrates on-chip H-bridge drive circuit designed with N-channel and P-channel power MOSFETs and is suitable to drive a brushless DC motor or a stepper motor winding. It has the wider operational voltage range (from 2V to 12.0V), its maximum continuous output current is up to 2.6A, and its maximum peak output current is up to 4A.The series circuit powered by VCC and VDD separate , which VCC is logic and control power supply, VDD is power supply. CXMD3286 CXMD3287 CXMD3288 has on-chip temperature protection function. When the load current of the drive circuit is much larger than the maximum continuous current of the circuit, the junction temperature of the circuit will be increased rapidly. Once the set value (150℃) is exceeded, the internal circuit will be closed immediately Off the output power tube, cut off the load current, to avoid the temperature continued to rise caused by plastic packaging smoke, fire and other security risks. Built-in temperature hysteresis circuit to ensure that the circuit is restored to a safe temperature before allowing the circuit to be re-controlled. CXMD3286 CXMD3287 CXMD3288 set a separate current sampling output pin, sampling output current sampling ratio of 1000: 1. The output sampling current for MCU analysis or control the external circuits to control the output current.
