Monolithic Power Systems (MPS) MP6570 3-Phase BLDC Controllers

Monolithic Power Systems (MPS) MP6570 3-Phase BLDC Controllers are high-performance motor controllers designed for three-phase PMSM and BLDC motors. The Monolithic Power Systems (MPS) MP6570 controllers feature field-oriented control (FOC) algorithms, SVPWM modulation, and a built-in angle sensor for precise control. The MP6570 operates in three modes: speed, position, and torque. Commands can be received via a digital interface or a PWM/clock input. A 10-bit ADC ensures accurate phase current sampling, while the SVPWM module modulates motor voltage with 12-bit resolution at a 20kHz switching frequency.
