IRMCK099M 5 www.irf.com ? 20 14 international rectifier december 18, 2014 1 overview irmck099 is a new generation international rectifier integrated circuit device primarily designed as a one-chip solution for inverterized appliance motor control applications. unlike a tradi tional microcontroller or dsp, the irmck099 provides a built-in closed loop sensorless control algorithm using the unique flexible tiny motion control engine (tinymce) for permanent magnet motors. the mce tm consists of a collection of control elements, motion peripherals, a dedicated motion control sequencer and internal memor y to map internal signal nodes. irmck099 also employs a unique single shunt current reconstruction c ircuit in addition to two leg shunt current sensing circuit to eliminate additional analog/digital circuitry. int egrated op-amps and a/d converter enable a direct shunt resistor interface to the ic. four analog inputs and up to eight digital i/o provide resources for application specific functions. figure 1 shows a typical application schematic us ing the irmck099. irmck099 contains 16 kbytes of otp program memory and comes in a compact 5mm x 5mm 32-pin q fn package. irmck099 power supply gate drive pm motor ipm or spm passive emi fillter digital i/o analog input host communication (rs232c) appliance pm motor drive 3.3v gate signal 15v eeprom 5 2 8 galvanic isolation optional figure 1. typical application block diagram using irmck099 downloaded from: http:///
