MP6570

3-Phase BLDC Controller with a

High-Accuracy Angular Sensor

DESCRIPTION

FEATURES

The MP6570 is a high-performance motor

controller that incorporates field-oriented control



3.3V Operating Supply Voltage

Flexible Parameter Configuration with Non-

Volatile Memory and Selectable

SPI/I²C/RS485 Interface

Embedded Accurate Angular Sensor with

Up to 14-Bit Resolution

(FOC)

algorithms,

SVPWM

modulation

technology, and an accurate embedded angle

sensor. The MP6570 is used for applications

with three-phase PMSM and BLDC motors.



Field-Oriented Control (FOC) Method

Position/Speed/Torque Operation Modes

PWM/Clock/Digital Interface Reference

Input

Energy Regeneration Braking Mode

10-Bit ADC with Programmble Gain

Up to 80kHz Programmble Switching

Frequency

A/B/Z Output with Internal Sensor Mode

Up to 32 Progarmmble Slave Addresses

Selectable Oscillator Source:

o Internal On-Chip Oscillator

o External Passive Crystal Input

Input Bus Over-Current (OCP) and Over-

Voltage Protection (OVP)

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 three-

phase 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.



Low-Power Standby Mode

Locked Rotor Detection and Restart

Programmable Over-Current Limit (OCL)

Threshold



Available in a QFN-32 (4mmx4mm)

Package

Non-volatile memory (NVM) is employed in the

MP6570 to store parameters programmed

through the selectable I²C, SPI, or RS485

digital interface.

APPLICATIONS



PMSM Motor, BLDC Motor

Application design is aided by the MPS

e.Motion Family Virtual Bench online developer

tool.

All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For

MPS green status, please visit the MPS website under Quality

Assurance. “MPS” and “The Future of Analog IC Technology” are registered

trademarks of Monolithic Power Systems, Inc.

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.
