General Description

The APX9266 is a single-phase full-wave motor driver for DC fan motor, and its speed can be controlled by PWM input signal. The output signal of this IC is the amplified hall input signal. It is suitable for both game machine and CPU cooler that need silent drivers. The device has lock protection function and the lock-restart timing can be tunable by CT capacitor. The device is also with thermal shutdown function. In normal operation, the supply current is less than 3mA, but in PWM=0 standby mode, it is just around 130mA. Moreover, this feature will shutdown HB, Amplifier, and FG. The APX9266 is available in MSOP-10 package.
