高分问题 hall ic工作原理

风扇hallic为双极驱动,即一个防波信号.
详细可以参照三洋电子的ic.它们忧很多的.在网上找一下就知道了.

Hall IC is the most critical drive device for direct current brushless motor fans. It is used to detectthe change in magnetic field and send a corresponding electrical signal, so the motor fan may maintain constant and stable operation. Every brushless motor fan shall contain one Hall IC.

With extensive design and manufacturing experience in Hall IC field, ATC is currently developing integrated peripheral drive device to simplify fan motor assembly procedures.
