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.
