Abstract
A current detecting device includes: a drive signal generating unit configured to generate a control signal based on a control voltage value indicating drive force to be applied to a target; a current detecting unit configured to detect a current value output based on the control signal generated by the drive signal generating unit; and a correction unit configured to correct the current value detected by the current detecting unit, based on at least a magnitude of the control voltage value.
Claims14
A current detecting device comprising:
- a drive signal generator, configured to generate a control signal based on a control voltage value indicating drive force to be applied to a target;
- a current detector, configured to detect a current value based on the control signal generated by the drive signal generator;
- and
- at least one processor, configured to correct the current value detected by the current detector, based on at least a magnitude of the control voltage value, wherein the current detector includes a shunt resistor, one end of the shunt resistor being connected to a power supply, configured to drive the target, and another end of the shunt resistor being connected to the drive signal generator.
