CIPOS Mini IM523 Series Increases Reliability and Performance for Low and Medium-Power Drive Applications
Infineon Technologies AG has launched the new IM523 series of the CIPOS Mini family that enables the integration of various power and control components to increase reliability, optimize PCB size, and system cost. These highly efficient IPMs (intelligent power modules) are based on the new 600 V Reverse Conducting Drive 2 (RCD2) IGBT technology, come with an open emitter, and 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 drives up to 1.4 kW.
The devices are available in different current ratings from 6 A to 17 A, with a breakdown voltage of 600 V. A built-in, UL-certified NTC thermistor for temperature monitoring, undervoltage lock-out (UVLO) at all channels, and overcurrent protection feature (OCP) further enhance the system reliability. The RCD2 IGBTs are combined with a full-featured, silicon-on-insulator (SOI) gate driver to enable lower power dissipation of the system. The three-phase inverter configurations with open emitters are integrated in a DIP 36x21 package. The package concept is specially adapted to power applications that need good thermal conduction and electrical isolation.
Package and mold compound offer improved humidity robustness. Additionally, the IPMs integrate a bootstrap circuit to simplify the PCB layout. The package concept is specially adapted to power applications which need good thermal conduction and electrical isolation. The series exhibits best-in-class switching loss, delivering excellent energy efficiency, especially in applications with high switching frequency.
