Abstract

See full text

According to one embodiment, a device for controlling motor driving which includes a first comparator, a second comparator, a zero level detecting portion, and a data determining portion is provided. The first comparator compares a voltage induced in a coil with a first threshold value. The second comparator compares the induced voltage with a second threshold value which is different from the first threshold value. The zero level detecting portion detects that a current flowing in an H-bridge circuit is zero. The data determining portion determines a value of digital data to be inputted to a DA convertor which generates a reference voltage for use in controlling a driving current of the motor based on an output of the first comparator, an output of the second comparator and an output of the zero level detecting portion.
