Infineon Technologies AG released the IM523 series on CIPOS Mini family. The highly efficient IPMs (Intelligent Power Modules) are based on the new IGBT 600 V Reverse Conducting Drive 2 (RCD2) technology and come with an open emitter. The CIPOS IM523 series allows the integration of various power and control components to increase reliability and optimize PCB size as well as system cost. The new IPMs are designed to control three-phase motors in low and medium power variable speed drives for Home appliances, HVAC (Heating, Ventilation and Air Conditioning)as well as for industrial fans and drive up to 1.4 kW.

RCD2 IGBTs are combined with a full-featured silicon-on-insulator (SOI) gate driver to allow lower system power dissipation. Three-phase inverter configurations with open emitters are integrated in a 36×21 DIP package. The package concept is specially adapted to energy applications that need good thermal conductivity and electrical insulation. As the series exhibits best-in-class switching losses, it provides excellent energy efficiency, especially in high switching frequency applications.

The devices are available in various current ratings from 6 A to 17 A, with a breakdown voltage of 600 V. Built-in, UL-certified NTC thermistor for temperature monitoring, undervoltage lockout (UVLO) on all channels, and the protection function from overcurrent (OCP) further increase system reliability. Packaging and mold components offer improved moisture resistance. Additionally, IPMs integrate boot circuitry to simplify PCB layout. Thanks to the industry-standard package, it is possible to easily and quickly convert the design of existing Mini IPMs (P2P) without redesigning the PCB, thus shortening the time to market.

The CIPOS Mini IM523 series can be ordered now; mass production has begun.
