AM5138 Motor Pre-Driver ICs Single Phase Full-Wave Motor Pre-Driver for Fan Motor AM5138 This is the summary of application for AM5138 optimum for driving 12V fan for general consumer equipment.

The most attractive function of AM5138 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 wh
