AM7228 Motor Driver ICs Single Phase Full-Wave Motor Driver for Fan Motor AM7228 This is the summary of application for AM7228 optimum for driving 12V fan for general consumer equipment.

The most attractive function of AM7228 is slope adjust by external resistor, that can meet most of fan request.

This IC employs soft switching drive, Bi-CMOS process, and realizes silent drive, low ON resistor, and low power consumption.

This also incorporate lock protection and auto restart circuit which doe
