24V from low voltage logic you can often meet this requirement using a potential divider to provide the mosfet with a gate voltage above 0V.ĭo you need to use a mosfet driver IC? If the mosfet has a high Gate switching current (e.g.
transient suppressor) or select a device with a higher rating. Will the power rails spike? If so provide protection of some sort (e.g. The Gate to Source max voltage (max Vgs) is a critical factor that must not be exceeded (even for a few nS) or the MOSFET can be destroyed. The Gate threshold voltage determines the voltage difference you need to apply to the gate to make the mosfet conduct. The Drain to Source max voltage rating (max Vds) determines the maximum voltage you can switch.
