Greetings,
I need to operate 40 independent solenoid devices(12V 250mA each) through a single circuit.
To turn them ON, 12V supply is required.
To keep them ON, 4V supply is the minimum requirement.
Since these solenoid devices remain ON for long duration of time I need to make a circuit that provides 12V for about 0.1ms (to turn on solenoid device) and then provide 4V (to keep them on).
Currently I'm using IRFZ44N MOSFETS (controlled switching through 74HC595) that are continuously providing 12V to the solenoid devices to keep them ON. Every solenoid device is independently operated and there is an instance where maximum 15 are continuously ON for 30 minutes.
Thus a lot of power is being wasted.
Kindly Advice.
Thank You.
