REFAIRCONC302AIM564TOBO1

REFAIRCONC302AIM564TOBO1 is a 3-phase turnkey motor drive reference design board. This board is for air conditioner outdoor units (ODU) with an IMC302 iMOTION™ controller, CIPOS™ Mini IPM IM564-X6D inverter with integrated PFC stage, 1ED44175 gate driver for PFC stage and CoolSET™ ICE5AR4770BZS for the auxiliary supply. It enables more efficient ODU designs with smaller form factors and provides fully-featured motor control (MCE2.0) for reduced development cycle time. The board is equipped with all assembly groups for sensorless FOC, and reserved interface for BLDC/AC fan control, relays and 4-way valve control and 3-ch temperature sensing circuits, so that it can be easily used for air conditioners and similar home applications. It provides a single-phase AC connector, an EMI filter and soft power-up circuit, input rectifier, DC bus capacitors, on-board PFC inductor emitter shunts for current sensing and OCP, thermistor output and a voltage divider for DC-link voltage measurement.
