My question pertains specifically to devices like an EcoSPARK®2 400V, N-Channel Ignition IGBT. I'm investigating the requirements for building an electronic ignition system for a go cart. This would energise the coil and thus generate a spark. You'd be firing at a maximum of 175Hz.
The datasheet uses the following test setup for inductive load testing:-
The datasheet also says that the IGBT has a logic level gate drive. And from the performance curves and switching characteristics table, it appears the RG = 1KOhm. I'm not sure how to assess it's 21 nC gate capacitance wrt other similar devices.
However this seems to contradict most of the answers on the IGBT tag. Lots of gate drive is recommended there for quick up and down switching. Some even suggest going below 0V to guarantee turn off. A 1KOhm resistor would cap the drive to an absolute limit of 5mA (5V logic) which doesn't seem a lot.
In all honesty, I had made preparations to use a TC4422 drive chip but maybe I don't need to. Is this just a newer form of IGBT and I can directly drive it from a micro controller output pin? Too good to be true?
