Yes the circuit will handle both low and high impedance injectors but only one injector per driver in either case. And the LM1949 can only handle a 4:1 peak/hold ratio so that somewhat limits the low impedance injectors that it can drive correctly. But most low impedance injectors require a 4:1 ratio.jharvey wrote:I forget if that can handle a high and low impedance injector. Can it do both? I like the SMT, looks much more packed together and cleaner. I'm curious how you plan to assemble them, do you have a reflow oven?nitrousnrg wrote:The P&H driver is based on jperf's circuit.
And I find it very annoying that people think they can use my design freely. Use the LM1949 data sheet and use the circuit shown there or use your own modifications. My design is not very different but it's still a design I developed for my own boards.
