Evaluation kit for EiceDRIVER™ 2EDN7524G dual-channel low-side non-isolated gate driver IC
The complete driving circuitry is integrated into the board to allow a simple and practical step-by-step discovery of the 2EDN7524G characteristic 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 MOSFETs in TO-220 package, which can be allocated on the board. For this purpose an Infineon CoolMOS™ or OptiMOS™ power MOSFET solution can be selected.
The evaluation kit requires an external function generator and a DC power supply to provide the input signals to the 2EDN7524G. 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 2EDN7524G 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.
