Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a motor driving current amplifier, a motor driving device, a driving method of the same, and a motor driving system, capable of being applied to a plurality of kinds of motors having different characteristics suitably and with high reliability, and of driving a motor with stability.SOLUTION: A motor driving device has: an output current ripple detector detecting an output current ripple to a motor to be a driving target; a PID controller modifying control characteristics for controlling an output current to the motor depending on the output current ripple detected by the output current ripple detector; a PWM controller receiving an output signal from the PID controller to perform PWM control; and a full bridge circuit in which switching elements are on/off-controlled depending on the PWM signal outputted from the PWM controller.
