I am looking for a low part count solution that when you Press the momentary push button switch a home built electro-magnet will be first sent a negative voltage then positive voltage with independently adjustable durations from 50 ms 400 ms. I have been looking at DC motor control IC's but i might be over thinking this. the magnet is under 1.5 amps at 12 VDC.
Button Push->Negative pulse->Positive Pulse->OFF
Any ideas?
Your help is greatly appreciated.
