WebJan 5, 2013 · 81 1 1 2. The underlying concept here is "high-side switching" vs "low-side switching". N-MOSFETs are controlled by Vgs. Their circuit is such that N-MOSFETs work as low-side switches. Your circuit is a high-side switch i.e. the source pin in N-MOSFET is not grounded and may have an unpredictable voltage. – akhmed. WebFurthermore, it is especially important to highlight for power applications, that MOSFETs have a resistive nature. The voltage drop across the drain source terminals of a MOSFET is a linear function of the current flowing in the semiconductor. This linear relationship is characterized by the RDS(on) of the MOSFET and known as the on-resistance.
