In this article, we will discuss the application field and working principle of FDMC86570L.

Application Field

FDMC86570L is suitable for various switch applications, such as power supply control, DC-to-DC converters and relay replacement. Its superior switching characteristics, small size and ESD protection make it well suited for use in a wide range of circuits, from high-power motor control to low-power audio circuits. Additionally, its compatibility with 3.3V and 5.0V supply voltage and its thermal superiorities make it suitable for applications such as DC-DC converter with fast switching speed and high current.

FDMC86570L is also a good option for mobile phone, notebook computer, PDA, and other electronic systems of low-voltage and low-power design. Its low-voltage working range and its small size make it suitable for low-current load switching and low-cost, low-power applications. Moreover, its low static power consumption makes it an ideal choice for power-saving applications.

Working Principle

FDMC86570L is a depletion-mode type MOSFET, and its working principle is based on the change in voltage applied to its control gate. When the voltage applied on the gate is lower than the source, no current flows from source to drain, and it is in the "Off" state. When the voltage is higher than the source, an inversion layer is formed in the channel between source and drain that allows current to pass, and the device is in the "On" state.

The gate current of FDMC86570L is very small, so it does not draw much current when it is in the "Off" state. Furthermore, the body diode of the FDMC86570L is reverse-biased, protecting the device from reverse leakage currents. Therefore, the device can be used in the reverse-polarity applications, such as PWM signal control.

The FDMC86570L comes with an ESD (electrostatic discharge) protection circuit, which protects the device from the overvoltage by diverting the current away from it. This ESD protection circuit will not affect the normal operation of the device, and it provides an additional safeguard against any unexpected damage to the device.

Lastly, the FDMC86570L is also an
