IRMCK099M

IRMCK099M is an iMOTION™ motor control IC for single motor drive. This is a low cost, high performance OTP memory based motion control ASIC designed primarily for appliance applications. This is designed to implement high performance control solutions for advanced inverterized appliance motor control. It 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. Typical applications are pumps and fans, drones, multicopters, home appliances, any other PMSM drive.

• TinyMCE dedicated computation engine for high efficiency sinusoidal sensorless motor control
• Internal oscillator – no clock required
• Built-in hardware peripheral for 1 or 2 shunt current feedback reconstruction and analogue circuits
• Supports both interior and surface permanent magnet motor sensorless control
• Loss minimization space vector PWM, internal ITRIP comparator
• Two-channel analogue output (Sigma Delta D/A), JTAG programming port for debugging
• UART and I2C serial interface, factory calibrated analogue inputs
• Capture input, watchdog timer with independent internal clock
• Standby low power mode, CRC memory check
• 32 lead QFN package, ambient temperature range from -40˚C to 125˚C
