MOSFETs for Seat Control

MOSFETs are also for power switching circuits. Unlike bipolar junction transistors (BJTs), the competing type of power transistor, MOSFETs do not require a continuous flow of drive current to remain in the ON state. Additionally, MOSFETs can offer higher switching speeds, lower switching power losses, lower on-resistances, and reduced susceptibility to thermal runaway. In switched-mode power supplies (SMPSs), MOSFETS are often used as the switching elements for regulation as well as for power factor correction (PFC).
