Description
IRMCK203 is a high performance digital motion control IC for Sensorless AC permanent magnet motor application. Control is based on closed loop vector control for sinusoidal Back EMF motors. With IRMCK203, the users can readily build a high performance Sensorless drive system without any programming effort and minimum start-up time. Built-in unique start-up and ramping algorithm enables wide application. This IC is versatile enough that the users can configure and optimize system performance according to the needs of each application. With International Rectifier iMOTION products including high voltage ICs such as IR2175 current sensing IC and IRAM series of Intelligent IGBT module in combination with IRMCK203, the end result is a fully optimized system with reduced electronics component counts. This simplifies the design for low cost Sensorless drive modules. IRMCK203 can be easily adapted to various permanent magnet motors through ServoDesignerTM tool, which is the fully configurable graphic user interface tool.

IRMCK203 Overview
IRMCK203 is a new International Rectifier integrated circuit device designed for one-chip solution for complete closed loop current and velocity control of a high performance Sensorless drive for PM motors. Unlike a traditional microcontroller or DSP, IRMCK203 does not require any programming to complete complex Sensorless algorithm development. Combined with International Rectifier's high voltage gate drive and current sensing IC, the user can implement complete speed control of PM motors with minimum component count and virtually no design effort. In addition to Sensorless closed loop speed control operation, features such as Start-up retry, Phase Loss detection, Low Loss PWM, Regeneration Braking control and various drive protections are all implemented inside IRMCK203. Analog and digital I/Os can also be configured. Host communication logic contains Asynchronous Communication Interface for RS232C or RS422 communication interface, a fast slave SPI interface and an 8 bit wide Host Parallel Interface. All communication ports have the same access capability to the host register set. The users can write to, and read from the predefined registers to configure and monitor the drive through these communication ports.
