Working Principle

MOSFETs operate according to the basic transconductance principle. Transconductance is the ratio of output current to the input voltage. Since the MOSFET is a voltage controlled device, the output current is a function of the voltage applied to its gate-source terminal. The gate-source voltage (Vgs) also determines the level of current flowing through the device. When the gate voltage is below the threshold voltage (Vth), the device is in its OFF state and the current through the device is zero. When the gate voltage is above the threshold, the device is in its ON state and the current is determined by the gate-source voltage.In the case of the DMP4047LFDE-7, the device is designed for low voltage applications and is able to handle currents up to 20A. The maximum drain current is 20A and the maximum power dissipation is 28W. The device has a very low gate threshold voltage of 2V and a very low RDS(on) of 0.24Ω. In summary, the DMP4047LFDE-7 is a high performance field effect transistor designed for low voltage switching applications. Its features include a low gate threshold voltage, high speed switching, high current handling and high power supply efficiency. It is ideal for a wide range of applications including switching regulators, current detection and automatic motor control.
