LA6584JA

Overview

The LA6584JA is Single-phase bipolar fan motor is put into silent driving by means of BTL output linear drive,

offering high efficiency and power saving by suppressing the reactive current. Lock protection and rotation signal (FG,

RD) circuits are built in, ensuring optimum application to small fans for notebook PC, consumer equipment power

supply, car audio system, CPU cooler, etc. that require high reliability and low noise.

Functions and Applications

• Single-phase full-wave driver for fan motor
