Infineon Technologies AG Evaluation Boards EVAL-1ED3142MU12F-SIC

The EVAL-1ED3142MU12F-SI C is in half-bridge configuration with two gate driver ICs (1ED3142MU12F) to drive power switches such as IGBTs, MOSFETs and SiC MOSFETs. This board comes pre-populated with two CoolSiC™ MOSFET IMZA120R020M1H, an additional gate driver IC is used for isolated over-current feedback signal from high voltage side to logic control side, fast operational amplifier is used as comparator for over-current detection. It is best suited for double-pulse testing. 1ED3142MU12F belongs to the EiceDRIVER™ Compact 1ED31xx family (X3 compact family). 1ED3142MU12F offers separate sink and source output, accurate and stable timing, active shutdown to ensure a safe power transistor off-state in case the output chip is not connected to the power, short-circuit clamping to limit the gate voltage during short circuit. The driver can operate over a wide supply voltage range, either unipolar or bipolar.
