IRMCK172M
High Performance Sensorless Motor Control IC
Description
IRMCK172M is a high performance One Time Programmable ROM based motion control IC designed and
optimized for appliance control which contains two computation engines integrated into one monolithic chip. One
is the Flexible Motion Control Engine (MCE^TM) for sensorless control of permanent magnet motors or induction
motors; the other is an 8-bit high-speed microcontroller (8051). The user can program a motion control algorithm
by connecting these control elements using a graphic compiler. Key components of the complex sensorless
control algorithms, such as the Angle Estimator, are provided as complete pre-defined control blocks. A unique
analog/digital circuit and algorithm fully supports single shunt or leg shunt current reconstruction. IRMCK172M
comes in a 48 pin QFN package.
Features
 MCE^TM (Flexible Motion Control Engine) -
Dedicated computation engine for high
efficiency sinusoidal sensorless motor control
 Built-in hardware peripheral for single or two
shunt current feedback reconstruction and
analog circuits
 Supports induction machine and both interior
and surface permanent magnet motor
sensorless control
 Loss minimization Space Vector PWM
 Two-channel analog output (PWM)
 Embedded 8-bit high speed microcontroller
(8051) for flexible I/O and man-machine control
 JTAG programming port for
emulation/debugger
 Serial communication interface (UART)
 I2C/SPI serial interface
 Internal 32Kbyte OTP ROM
 3.3V single supply
