The BA6428F is a single phase full-wave fan motor driver.
It has motor protection functions such as a lock detector,
automatic restart, and an output terminal that alarms
when the motor is locked. This IC makes sets smaller,
due to the compact SOP8 package and the requirement
of few external components.
