Function

The AM9789 is a single-phase, full wave motor

driver suited for DC fan motor, and its speed is

controlled by PWM input signal. It is suitable for

both game machine and CPU cooler which need

silent drivers. It features lock protection, thermal

shutdown, PWM control, low noise and so on.
