两相直流无刷马达驱动电路

MXT276/277 集成霍尔传感器和输出驱动电路，主要应用于无刷直流风扇的电转换。此款IC 集成了稳压电路、保护二极管、霍尔传感器、运算放大器、比较器和一对互补的开集电极输出（DO，DOB）。当磁通量密度（B）大于操作点（BOP），DO 就会开启（低电平），同时DOB会关闭（高电平）。两个输出管脚的状态会一直保持到B 低于释放点（BRP），这时DO、DOB 改变各自的输出状态。对于直流风扇的应用，有时会发生电源反接的情况。内部二极管只能给芯片提供保护而不能给线圈提供保护。所以应用的时候，有必要附加一个外部的二极管，它在电源反接的时候给线圈提供保护。 ·片上集成霍尔传感器\r\n\r\n·3.5V~20V 的操作电压\r\n\r\n·300mA 的平均输出沉电流\r\n\r\n·内置保护二极管保护芯片电源反接的情况\r\n\r\n·-20℃~85℃操作温度\r\n\r\n·小型TO94 封装形式;
