This evaluation kit provides a test platform for Infineon’s single-channel non-isolated gate driver IC with truly differential inputs EiceDRIVER™ 1EDN7550B in SOT-23 6pin package.
The complete driving circuitry is integrated into the board allowing a simple and practical step-by-step discovery of the 1EDN7550B characteristics and the evaluation of the influence of the surrounding driving circuitry on the signal delivered to the load. The driver is intended to feed a low-side MOSFET in TO-220 package. For this purpose an Infineon CoolMOS™ or OptiMOS™ power MOSFET solution can be selected.
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 1EDN7550B 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.
Moreover, the evaluation kit allows to evaluate the robustness of the 1EDN7550B to DC ground shifts, which is the key strength of the arising driving concept with truly differential inputs. The board provides, in fact, the possibility to differentiate the ground voltage of the driver and its input stage reference voltage (ground of the function generator).
