INFINEONEVAL1ED3890MX12MTOBO1Evaluation Board For EiceDRIVER Half-Bridge Driver for Drives, EV Charger, Motor Control &

Evaluation board for EiceDRIVER™ X3 single-channel highly flexible isolated gate driver family

The EVAL-1ED3890MX12M is in half-bridge configuration with two gate driver ICs (1ED3890MX12M) to drive power switches such as IGBTs, MOSFETs and SiC MOSFETs. The switch type can be freely chosen. The board has a size of 85 x 85 x 15 mm without any power switch assembled.

The board is best suited to leverage the highly configurable X3 Digital (1ED38xx) family with its rich feature-set. Configuration is performed via I2C bus.

The evaluation board is recommended to be used with a companion microcontroller evaluation board EVAL-1ED38X0DCT to optimize the configuration process.
