DESCRIPTION

The MP6570 is a high performance controller

using field-oriented-control (FOC) method and

accurate on-chip angular sensor. It is used in

applications with 3-phase PMSM and BLDC

motors.

The FOC control, widely used and perfect to get

high performances of motors, provides higher

dynamic response, lower torque ripple and higher

efficiency. MP6570 can be operated in position

control or speed control mode or torque control

mode. The reference command come from digital

interface input or external single input signal either

in clock or PWM input. The motor 3-phase current

is sampled and digitalized to the current/torque

control loop by 10-bit ADC. With FOC algorithm,

the motor 3-phase winding voltage is modulated

through SVPWM module which has up to 12-bit

resolution at 40 kHz switching frequency.

The on-chip angular sensor is using MPS high

speed & accuracy angular sensor as rotor position

and speed feedback. It has up to 500kHz data

refresh rate and 10-bit position resolution which is

perfect to BLDC & PMSM motor control especially

in the applications , i.e., high speed control and

high position accuracy servo.

MP6570 has non-volatile memory which is flexible

interface. In addition, all control and design with

MP6570 can be easily done with MPS GUI

Software.

The MP6570 has robust failure mode protection

including over-current protection, over current

protection, over temperature protection and input

bus over-voltage and over-current protection. The

MP6570 is available in QFN4x4-32 package.
