Abstract:
A fan apparatus has a drive circuit for an electrically-driven rotor, and includes a drive signal generating circuit portion for the electrically-driven rotor; an output stage including an upper MOSFET and a lower MOSFET; and a motor portion to be driven by the output stage. One of the upper MOSFET and the lower MOSFET is a braking MOSFET, while another of the upper MOSFET and the lower MOSFET is a non-braking MOSFET. The fan apparatus further includes a back-electromotive force supply portion arranged to supply, to the braking MOSFET, power by a back-electromotive force caused by rotation of the motor portion while a power supply voltage for the electrically-driven rotor is not being supplied; and an electromagnetic brake portion arranged to electromagnetically brake the motor portion by causing the braking MOSFET to enter an ON state through the power supplied by the back-electromotive force supply portion.

Claim (Index 5):
The fan apparatus according to  claim 4 , wherein a breakdown voltage of the constant voltage diode is determined on a basis of the control power supply voltage generated from the power supply voltage.
