Re: 4-channel hi-impedance injector driver
Hello !
I'm looking to drive extra injector on my motor and this board seems very interesting.
The output from my ECU (not a secu-3 one) is 0 to +1v. Is it a sufficient voltage to drive it ? It seems the input treshold voltage is 0.5v but I'm really not sure.
In this case, are R5 & R6 1k usefull or not ?
Thanks for your help and thanks for your share

Hi,
1V is not sufficient to drive FET (even FET with logic level driving), You should boost your signal using a bipolar transistor (or something else which is able to be driven by 1V level).

These resistors are intended to pull up inputs to ground, which may be required for ECUs with high side outputs (SECU-3 unit has two high side outputs).In this case, are R5 & R6 1k usefull or not ?

Re: 4-channel hi-impedance injector driver
Thanks for quick reply,
Which minimum (and maximum) target voltage should I reach ?

Re: 4-channel hi-impedance injector driver
See VN14NV04 datasheet.
Input threshold voltage: min 0.5V, max 2.5V. So, input level must be at least 2.5V for correct operation of transistor.
