DESCRIPTION The MP6570 is a high-performance motor controller that incorporates field-oriented control (FOC) algorithms, SVPWM modulation technology, and an accurate embedded angle sensor. The MP6570 is used for applications with three-phase PMSM and BLDC motors. The operation of the MP6570 supports three modes, including speed mode, position mode, and torque mode. The reference command comes from either the digital interface or the pulse-width modulation (PWM)/clock input pin. A 10-bit ADC is employed for accurate sampling of each phase current. The threephase voltage of the motor is modulated through an SVPWM module, which has up to 12-bit resolution at a 20kHz switching frequency.
