MOTOR DRIVING CIRCUIT

PROBLEM TO BE SOLVED: To control a motor in response to a proportion of an H-level and an L-level in a PWM signal without depending on a voltage level of the pulse signal. SOLUTION: A motor driving circuit includes a voltage conversion circuit for outputting a predetermined first voltage if an input...

Zusammenfassung:PROBLEM TO BE SOLVED: To control a motor in response to a proportion of an H-level and an L-level in a PWM signal without depending on a voltage level of the pulse signal. SOLUTION: A motor driving circuit includes a voltage conversion circuit for outputting a predetermined first voltage if an inputted pulse signal has one logic level, and outputting a predetermined second voltage if the input pulse signal has the other logic level; and a driving control circuit for controlling the driving a motor coil on the basis of the first and second voltages to be outputted from the voltage conversion circuit.
