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.

A high-speed high-accuracy magnetic angular

sensor is embedded in the IC for rotor position

and speed feedback. The position sensor has a

data refresh rate up to 1MHz and up to 14-bit

position resolution, ideal for BLDC and PMSM

motor controls, especially in applications that

require high speed or position accuracy.

Non-volatile memory (NVM) is employed in the

MP6570 to store parameters programmed

through the selectable I

2C, SPI, or RS485

digital interface.

Application design is aided by the MPS

e.Motion Family Virtual Bench online developer

tool.

Full protection features include over-current

protection (OCP), rotor-lock protection, and

input bus over-voltage (OVP) and over-current

protection (OCP).

The MP6570 is available in a QFN-32

(4mmx4mm) package.
