KIT_DRIVER_2EDF7275F

This evaluation kit provides a test platform for the Infineon's dual-channel functional isolated gate driver IC EiceDRIVER™ 2EDF7275F belonging to the EiceDRIVER™ 2EDi family of isolated gate drivers. 

The complete driving circuitry is integrated into the board to allow a simple and practical step-by-step discovery of the 2EDF7275F characteristics and to evaluate the influence of the surrounding driving circuitry on the signal delivered to the load. The dual-channel driver is intended to feed two low-side or high-side MOSFETs in TO-220 package, which can be allocated on the board. For this purpose a  CoolMOS™ or OptiMOS™ power MOSFET solution from Infineon can be selected.

The evaluation kit requires an external function generator and a DC power supply to provide the input signals and the supply voltages to the 2EDF7275F. As shown in the quick start guide, the easiest and immediate way-to-use the board is with zero-power applied to the MOSFETs. In that operating condition, the 2EDF7275F load is equivalent to a pure RC filter. Testing with different MOSFETs is a suggested option to evaluate and understand the impact of the MOSFETs input capacitance on the driving timing behavior.

Additionally, the possibility to power-up the MOSFETs and then, trigger the switch of the devices is purposely provided through banana connectors. An external circuitry must be properly built in that case to provide the bulk voltage and limit the current. Furthermore, pads for a possible connection to a daughter card are included.
