#175199 - Ready made solenoid drivers
Responding to: ???'s previous message
Yeah I have been already looking into these drivers but the problem with these drivers is once i my TTL input goes high the output makes the valve ON and OFF at a frequency and duty cycle determined by values of capacitance and resistors connected to the different pins and when TTL goes low the valve remains in the normal default state(close/open)

But my requirement is i want the valve to remain open continuously until the TTL goes to low.

Only option with these drivers is to make duty cycle 100% .But i am not sure whether it is possible practically ..they have resistors listed upto 95 % duty cycle .

I am also wondering how these drivers are classified because i see many types all looking similar.
some are called low side driver and some are called high side driver???
