IRMCK201 is a complete AC servo motor control IC. It contains closed loop current control for sinusoidal AC current, and
closed loop velocity control based on encoder position feedback interface. A standard communication port is provided for
RS232C or RS422, in addition to a fast SPI communication interface. Unlike a traditional DSP or a microcontroller, the
IRMCK201 does not require any programming effort to complete the complex control algorithm. It allows users to configure
the algorithm for specific application needs. Permanent magnet motor or AC induction motor are supported. IRMCK201
facilitates high performance servo design together with the IR2175 current sensing IC and IR213x high voltage 3-phase gate
driver IC, which simplifies the hardware design while minimizing cost. For multi-axis applications, IRMCK201 can be used
as a multi-drop slave drive based on the SPI protocol. The package is available in a 100-pin QFP.
