Abstract: PROBLEM TO BE SOLVED: To provide a multi-mode motor controller architecture whose form is easily repetitively changeable so as to be operated in a plurality of operation modes, and which is allowed to be operated relating to a wide-range controller circuit. SOLUTION: The multi-mode motor controller architecture has a motor, an integrated circuit controller, and an integrated-circuit driver circuit. The integrated circuit controller has a pulse generator, DAC, ADC, and a digital compensator circuit. The integrated-circuit-driver circuit is in a communicating state with the controller; and has an error amplifier, a first and second output amplifier to drive the motor, and a sense amplifier. The motor controller architecture is configurable so as to be operated in a linear mode, a pulse mode, or a switchable linear/pulse mode. The controller architecture is, for example, allowed to be obtained with an external compensation circuit of a resistor/ capacitor circuit or the like, or with a digital compensation circuit positioned within the controller integrated circuit.
