Fast switching of high load using an IGBT I want to control a high load with fast switching times (motorbike ignition coil) using an arduino. I found an IGBT that claims to be purpose built for that use case (ISL9V3040P3). This IGBT has an Vge (th) max of 2.2 V, so I thought I could simply switch the Gate with an Arduino Pin.
But I did some more digging and most people seem to use an additional IGBT driver (like IR2127PBF). What´s the reason for that? Is it because the arduino can´t provide sufficent current?
One of the key requirements for IGBT driver circuits is
that enough current be supplied to charge and discharge
the input capacitance of the IGBT and thus to switch the
IGBT on and off at very high Switching rates.
