Infineon Technologies 1ED3121Mx12H | Demoboard EVAL-1ED3121Mx12H

Description

The EVAL-1ED3121MX12H is in half-bridge configuration with two gate driver ICs (1ED3121MU12H) to drive power switches such as IGBTs and SiC MOSFETs. This board comes with TRENCHSTOP™ IGBT IKQ75N120CH3. 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. This board is best suited for double-pulse testing.1ED3121MU12H belongs to the EiceDRIVER™ Compact 1ED31xx family (X3 compact family). 1ED3121 offers separate sink and source output, accurate and stable timing, active shutdown to ensure a safe IGBT 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.
