【应用】60V汽车级MOSFET P64LF6QNK用于40W电子水泵控制器,具有体积小、裕量大等优势
汽车电子水泵的功率都比较小,一般在1000W以下范围,电机一般采用直流无刷电机。 电子水泵具有结构紧凑,使用方便,功能强大,寿命长,性能稳定,低噪音、低耗能、高效率等诸多优点。而直流无刷电机驱动一般会采用三相全桥进行驱动,目前市场上有些控制芯片内部集成三相桥直接驱动电机,但是功率等级一般低于15W。本文将介绍40W水泵的直流无刷电机控制器,外部扩展MOSFET,供电电压为24VDC,系统框图如图1所示。
图1: 40W电子水泵控制器系统框图
图2:三相全桥主回路
三相全桥中的功率器件采用新电元的60V汽车级MOSFET P64LF6QNK,能够适应24V系统。另外其结构紧凑,采用独特的MO-235B封装,最大漏级电流64A,符合ROHS无铅标准。下面介绍其作为电子水泵应用器件的几点优势:
•通过车规级认证,满足可靠性要求;
•存储温度及工作温度范围均为-55℃~175℃,能够适应燃油发动机的发热引起的高温环境;
•采用薄型SMD封装,结构紧凑,占用PCB面积较小,有效降低产品整体尺寸;
•漏级电流64A,对于40W,24V供电应用有足够大的裕量。且RDS仅为4.5mΩ,有助于降低MOSFET在工作时的自身发热,提高效率。
