IRMCK182M
High Performance Sensorless Motor Control IC
Description
IRMCK182M is a high performance One Time Programmable ROM based motion control IC designed
primarily for appliance applications 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. IRMCK182M comes in a 32 pin QFN 5x5 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
• 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)
• Watchdog timer with independent internal clock
• Internal 32Kbyte OTP ROM
• 3.3V single supply
