MOSFETs are usually the preferred switching devices to be included in PICs for applications below 100 V. MOSFETs,as PICs main power switching cell, either in a lateral(LDMOS) or in a vertical structure (VDMOS), present two important advantages: (1) extremely low switching times;(2) less complex drive, control and protection circuits, laid into a few mm2 area in the same monolithic circuit.
