Description
This is the summary of application for AM7232S optimum for driving 12V fan for general
consumer equipment. The most attractive function of AM7232S 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 does not require external capacitor.
