Description

The Infineon REF-SMD5KIMSQM2INV 3-Phase Inverter Power Board evaluates Infineon CoolSiC G2 MOSFETs in an integrated servo drive application. It features a small heat sink, eliminating the need for a cooling fan, and includes a complete 3-phase inverter on a single 4-layer FR4 PCB. The driver circuit uses the EiceDRIVER 1ED3322MC12N isolated gate driver with DESAT protection and Miller clamp, and the power switch is a CoolSiC IMSQ120R012M2H MOSFET in a Q-DPAK dual half-bridge package.
