If you need to drive both MOSFETs from a common signal you have to tie the sources together or the body diodes will stop you turning them off. Every MOSFET has a diode in parallel with the drain and source electrodes. The gate drive needs to either have a floating source applied between the common source and the common gate. flatland by abbott
