You might dig into the "Megasquirt" EFI control development,
and see what they use for low impedance injector options.
Paralleling a "peak" driver (no DC limiting) and a "hold"
driver (DC limited pulsed current source) is how I've done
a few peak/hold designs. You simply have to have a pulse to
control the peak path, that doesn't let the injector solenoid
go overcurrent.
I expect Delphi, Bosch, those kinds of folks are the bigger
players when it comes to automotive related application
drivers.
