IRMCK099M
High Performance Sensorless Motor Control IC
Description
IRMCK099 is a low cost, high performance OTP memory based motion control ASIC designed primarily for
appliance applications. IRMCK099 is designed to implement high performance control solutions for advanced
inverterized appliance motor control. IRMCK099 contains the flexible Tiny Motion Control Engine (TinyMCE) for
sensorless control of permanent magnet motors over the full speed range. The TinyMCE implements sensorless
Field Oriented Control using single or leg shunt current feedback by a combination of hardware and IR-supplied
firmware elements. Key components of the complex sensorless control algorithms, such as the Angle Estimator,
are provided as complete pre-defined control blocks. The ASIC is designed to eliminate external components and
reduce cost by including an A/D converter, analog amplifiers, an overcurrent comparator, watchdog timer and
internal oscillator. Strong startup and configuration tools get the motor running quickly without any programming.
A standby power mode can help to increase overall system efficiency. IRMCK099 comes in a 5mmx5mm, 32 pin
QFN package.
