For a one-off project I'd like to switch about 30 solenoids (12 V, 1 A) with pulses between 20 and 50 ms duration (duty cycle < 10%) generated by an AVR processor.
One solution would be an optocoupler that is able to drive the load directly. This is attractive for its simplicity (I expect to hand-solder 30+ of the circuits) and the galvanic separation of the
12 V from the logic, though the latter would not be strictly necessary.I have found one available part, PVG612 (data sheet at
So I've been looking for alternatives but come up empty so far. Any tips?
