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.
