The compact boards provide easy-to-use power stage, good light-load efficiency and reduce footprint while improving reliability

Designed for rotary refrigerator compressors, here are two new reference boards by Infineon Technologies AG for low-power compressors. These can be easily used for building final mass-production application boards, enabling product developers to drastically reduce the system development time.

The REF_Fridge_D11T_MOS is a ready-to-use three-phase inverter including the iMOTION Smart Driver IMD111T-6F040 and the 600 V CoolMOS PFD7 superjunction MOSFET IPN60R1K0PFD7S. The board provides an easy-to-use power stage based on the iMOTION smart driver that combines ready-to-use FOC motor control algorithms with a 600 V phase gate driver in the LQFP-40 package. It also includes the discrete CoolMOS superjunction MOSFET with lowest Q rr, ESD protection and a compact SOT-223 surface mounted device (SMD) package. The board can be easily interfaced through iMOTION Link and enable the best light-load efficiency as well as a compact design.

REF_Fridge_D11T_MOS

The reference design REF_Fridge_C101T_IM231 is ideal for customers aiming for a higher level of integration and a reduced footprint. The board combines a digital motor control IC (iMOTION) IMC101T-T038 with a three-phase CIPOS Micro intelligent power module based on a 6 A, 600 V IGBT. This combination provides a fully-featured compact inverter solution for low power motor drive applications. Furthermore, it reduces BOM count and PCB size while improving reliability.

REF_Fridge_C101T_IM231

With these solutions, Infineon stands true to its motto “From product thinking to system understanding.” The REF_Fridge_D11T_MOS and the REF_Fridge_C101T_IM231 are now available.
