BA6427F
Motor driver ICs
Single-phase full-wave motor driver
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 ponents 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. FApplications Single-phase, full-wave fan motors FFeatures 1) Equipped with lock detection and rotational-speed sensing functions. 2) pact SOP-8 package reduces the number of external ponents for a reduced mounting area. FAbsolute maximum ratings (Ta = 25_C)
3) Automatic restart when the motor lock is undone.
