Single-phase brushless fan motor is investigated in this thesis and is fabricated by UMC 0.5 m double-poly, triple-metal, N-Well CMOS process for notebook micro fan motor applications. H-bridge and embedded power mos architecture are used in implemented driver circuit, and an external capacitor is needed for pulse width modulation speed control. A comparator with hysteresis and digital lock detection and auto self-restart function are also implemented in this thesis. Besides, in order to prevent the rush current in output stage, the switch operation of power mos transistors are controlled individually.
