Hi Leramuer, sounds like the magic smoke escaped from that device. 12v x 1.8 a
= 21.6 watts, I assume thats the running current under normal load. That figure increases exponentialy when you reverse direction and that's a whole lot of heat. What do you have for a heat sink? Maybe in addition to more heat sink you should put in a thermal shutdown circuit.
