The Future of Analog IC Technology
The MP6570 is a high performance controller using field-oriented-contro l (FOC) method and accurate on-chip ang ular sensor. It is used in applications with 3-phase PMSM and BLDC motors.
The FOC control, widely used and perfect t o get high performances of motors, prov ides higher dynamic response, lower tor que ripple and higher efficiency. MP657 0 can be operated in position control o r speed control mode or torque control mode. The reference command come from d igital interface input or external sing le input signal either in clock or PWM input. The motor 3-phase current is sam pled and digitalized to t
