injector driver
(OP)
Hi.
I need to build an injector driver circuit for two bosch injectors: 0 280 155 965 and 0 280 1150 749.
Both are high impedance injectors (15 ohm). My choice is using an LM 1949 as injector driver.
My question is: can i use peak and hold mode with this injectors or do i need to drive them with full current all the time the pulse widht lasts?
Thanks.

RE: injector driver
You can use the peak & hold function but why bother? The transition always creates a non-linearity in the fuel delivery curve.

RE: injector driver
LM1939 can be used for saturated driver too.
