Single Phase Full-Wave Motor Driver for

Fan Motor AM7301

High efficiency, Rotation speed adjustable application for AM7301 optimum for driving 12V

fan for general consumer equipment. This IC employs soft switching drive, turbo start,

Bi-CMOS process and realizes silent drive, low ON resistor, and low power consumption.

This also incorporate lock protection and auto restart circuit
