Abstract
A motor-driving circuit drives a plurality of motors of different types. The motor-driving circuit includes a plurality of H-bridge circuits for outputting driving signals to the motors, a controller for controlling the plurality of H-bridge circuits, a setting section for setting up the controller, and terminals for inputting setting data.
Claims19
A motor-driving circuit for driving motors, comprising:
- a plurality of H-bridge circuits for outputting driving signals to the motors;
- an H-bridge controller for controlling the H-bridge circuits;
- and
- an H-bridge setting section for setting whether a plurality of H-bridge circuits should be independently driven or a plurality of H-bridge circuits should be driven in combination for driving a motor based on data of motor types driven in the H-bridge circuits,
- wherein the motor-driving circuit inputs a mode signal indicating whether a mode is a low power consumption mode or a normal mode, and
- wherein the H-bridge setting section performs setting whether a plurality of H-bridge circuits should be independently driven or a plurality of H-bridge circuits should be driven in combination for driving a motor in case that the mode signal indicates the low power consumption mode.
