® RT8720A Single-Phase Full-Wave Fan Motor Driver General Description The RT8720A is a single-phase driver IC for fan motors.
Rotation speed is controlled by supply voltage modulation and PWM input signal.
The RT8720A provides several protection features 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.
