I'm making my own board to make it PnP...
the ignition coil (wasted spark : 1-4 & 2-3) on my car appear to be controlled by signal (gnd ?) pulse
here is a similar ignition coil
(simplified scheme on my car)
55 and 37 are the two pin from the ECU, 3 is 12V
inside the original ECU, there is a mosfet for each connection (connected to the drain pin), and the source pin is connected to the gnd of the ECU via a big resistor
so I cant use the chip TC4424A for my board.
My question is could I use the same injector driver, the chip VNLD5090 to pulse signal to the ignition coil ?
