Driving multiple electromagnets

[lpsd]

@johnerrington

At 250mA Vces is 1.2V; if all 5 electromagnets are on you have 1.2V * (5*0.25A) = 1.5W
that is pushing the power dissipation for the chip.
You could glue on a small heat sink.

Thank you for this information, didnt even think about that. I dont think I will run them all together much, but I will definitely check that it doesn`t overheat.
