I want to use the LTC2662 to drive small (<50mA, >250Ohm) proportional solenoid valves.
Due to the inductive nature of the load, is it recommendable to usea) a capacitor in parallel to compensate step-increases in current?b) a fly-back diode?
What would be the advantages or disadvantages?TIA, Beat
Ok, I believe I can answer b) after re-thinking it: Because the voltage spike is going directly to ground, a fly-back diode is not necessary for this configuration.Right?And I will re-word a):Is it possible to avoid the transient open-circuit fault signal that follows a step-increase in current? If so, how and is there anything to be gained from it (faster settling, for instance) other than triggering the signal?
