ABSTRACT:
A brushless motor driving device includes a comparator. The comparator compares a control voltage with a control signal in proportion to a control current of each Hall element. An output of the comparator is amplified by a Hall element driving amplifier, and is inputted to a control current terminal of each Hall element as an error signal. Each Hall element outputs a Hall signal based on an inputted error signal. The driving voltage is controlled such that an amplified Hall signal matches with a driving voltage applied to each driving coil. The brushless motor driving device permits a brushless motor to be stably driven at any rotation speed from low-speed rotations till high-speed rotations with a simple circuit structure.
