EVAL-1ED020I12F2-DB

Überblick

Isolated gate driver daughter board using 1ED020I12-F2 to evaluate 1200 V CoolSiC™ MOSFET

The EVAL-1ED020I12F2-DB is part of the CoolSiC™ evaluation platform second revision in a high-side / low-side configuration with two gate driver ICs (1ED020I12-F2). This platform is developed to show the optimal driving of the CoolSiC™ MOSFETs or other power switches like IGBT and MOSFET in TO247 3-pin or 4-pin package. To achieve this target the design was split in two boards, one motherboard EVAL-PS-DP-MAIN and one daughter board, EVAL-1ED020I12F2-DB. The modular approach enables future expansion of the platform with additional gate driver cards. The switch type can be freely chosen.
EVAL-1ED020I12F2-DB contains the EiceDRIVER™ Enhanced isolated driver 1ED020I12-F2 with an integrated active Miller clamp preventing parasitic turn-on and DESAT function to protect against damage through short circuit, best suited for double pulse testing and evaluation.
