I am trying design an auto polarity for a 9V battery. This allows the user to insert the battery either direction and the circuit will compensate and switch the polarity. I found this H-Bridge design that works some of the times. However, every now and then, the mosfet will smoke and I am not sure if it is caused by a race condition in switching the mosfets.
Does anyone have any idea of a better design or a modification to this design to stop the mosfet from smoking. . Attached is the schematic.
