Datasheet	RT8723-Richtek.pdf

The RT8723 is a single-phase driver IC for fan motors.

Rotation speed is controlled by supply voltage modulation and PWM input signal.

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

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