Datasheet	RT8720B-Richtek.pdf

The RT8720B is a single-phase driver IC for fan motors.

Rotation speed is controlled by supply voltage modulation.

In the supply voltage control application, the fan speed slope is adjustable by the external voltage input.

including lock protection, thermal shutdown, over-current protection and under-voltage protection. In thermal shutdown mode, the supply current is less than 100μA. The rotation frequency is generated by FG output.
