hey , so for my company , I need to make board . the previous board I was using could drive 8 solenoid valves but for my latest design I just need to drive 2 solenoid valves . my past board was good enough ,Its size is issue right now so i would like to decrease the size of my board . the current suggestion i have got is using a ir2111 to drive my solenoid valve but currently I do not want to use mosfet's to drive my solenoid valve . any way to use the ic without mosfet?
I am using SY5220-5LZ-O1 as my solenoid valves it takes just 18 mA .
Are there any cheap and reliable ways to make a size efficient solenoid valve driver . if any suggestion please let me know.

 

Could use the low side or high side output directly to activate the solenoid with the IR2111.
What is the source of the input voltage?

I am giving signal from my microcontroller
could you help me with a circuit diagram for the ic

 

The IR2111 is intended for a different application, , what is wrong with a simple Mosfet, or even a small relay ?
You may get away with a simple 2n7000 at that current, which seems rather low, BTW?
Appears to be a pilot valve?

and i am giving power from a 24V battery

 

A small MOSFET is the way to go. A logic-level device direct from the micro-controller (or whatever you are using) should be OK. Don't forget the back EMF catching diode.

mosfet would need isolation
could you tell me a way so that i could make this work
or is it possibile to drive using switching from ho to lo using input signals

 

Why are you double POSTING!

 

Why would mosfet need isolation?
Why would you think that IR2111 provides any isolation?

 

Why would it need isolation, any more than the IR device?
And require more components??

 

If you want isolation - which is always a good idea, I would use a small SSR (Solid State Relay).
Like this, for example.

sadly solid state relay is not available right now so , so thats not a option as dont have time to wait

i need isolation in my circuit
so i would rather opt for something which is already isolated

 

You haven't given the reason for requiring isolation, ?
What would it be?
A small opto isolator would provide it.
e.g. 4n35, PC817

 

One fix.

 

Max, won't that exceed the gate limit voltage. Add another 10K between gate and ground.

 

I don't see it in the spec's I have?

 

+/- 20 volts gate limit.
Wouldn't that circuit place 24 volts on the gate when activated?
