The board at a glance
The evaluation board “EVAL-1ED020I12F2-DB” is part of the CoolSiC™ evaluation platform second revision.
This platform was developed to show the optimal driving of the silicon carbide CoolSiC™ MOSFETs or other
power switches in TO247 3-pin or 4-pin package. To achieve this target the design was split in two boards, one
motherboard (evaluation platform) “EVAL-PS-DP-MAIN” and a flexible driver-card, e.g. (evaluation board
“EVAL-1ED020I12F2-DB”). The modular approach enables future expansion of the platform with additional gate
driver cards. This means, the driver card is connected to the motherboard via connectors. In this way it is
possible to have different driver cards with of course different drivers which can work with one motherboard.
The power switches can be connected via connectors as well.
The first driver card, based on the evaluation platform second revision, contains the EiceDRIVER™ IC 1ED020I12-
F2 with an integrated active Miller clamp preventing unintended turn-on and a DESAT pin to protect the
application against damage through short circuit.

platform.
