Classification: CPC H | IPC H

Claim 2:
3. The current control circuit according to claim 1, the current control circuit being configured to further perform
a third mode of conducting a constant current control of the drive current so that the current value of the drive current maintains the second target current value after the current value of the drive current reaches the second target current value, the current control circuit further comprising:
a second comparison unit of comparing the current value of the drive current with the second target current value, and outputting a second comparison output signal of releasing the on-state of the holding circuit from holding when the current value of the drive current exceeds the second target current value,
wherein the holding circuit performs the constant current control to cause the current value of the drive current to maintain the second target current value, in the third mode, by releasing the on-state of the switch from holding at a timing when the second comparison output signal is output from the second comparison unit and holding the on-state of the switch at a timing when the on-signal is output from the on-signal output unit.
