1-Phase Full Wave Fan Motor Driver 8-Pin SOP T/R

The BA6427F is a single-phase full-wave motor driver for fan motors. By using this driver, a single-phase, full-wave motor driver circuit can be built with fewer components than a circuit using operational amplifiers. Lock detection and automatic restart mechanisms, which are required for fan motors, are also built in. A rotational-speed sensing output pin is provided for Ho output

• Equipped with lock detection and rotational-speed sensing functions
• Compact SOP-8 package reduces the number of external components for a reduced mounting area.
• Automatic restart when the motor lock is undone.
