• Mobile: FDB3860 is widely used in notebook computers, tablet computers and other products.
• Multimedia communication: With the rapid development of multimedia communication technology, FDB3860 is applied to the mobile phones, PDAs and other products.
• Computer: The FDB3860 is often employed to the many desktop and laptop computer that helps to reduce power consumption.
• Digital home: FDB3860 is widely used in TV set-top box, music centers, DVD players and many other products.

Working Principle
FDB3860 is composed of source-drain diffusion resistors, gate oxide layer and gate drain electrode. When a small voltage applied the gate, a channel is created between the source and the drain which allow current to flow. The current flow is controlled by the applied gate voltage. Usually, FDB3860 works with a gate voltage of 0.35V-2V and drain voltage of 5V-20V.In normal usage, the FDB3860 MOSFET as a switch can open or close circuit. When a small current applied to its gate terminal, it can switch resistive load of up to 5A. Because of its low on-state resistance, it can handle a relatively high current load. The FDB3860 is particularly suitable for "hot plugging," a switching system that quickly switches high current loads.

Advantages of FDB3860
FDB3860 has many advantages to offer, such as:

• Low on-state resistance, leading to less power consumption.
• High switching speed, which helps to improved system performance.
• Low threshold voltage and low drain-to-source leakage current, improving the power conversion efficiency.
• Good static and dynamic characteristics, providing good low voltage operation.
• High breakdown voltage, allowing the MOSFET to be used in breakdown circuits.
• Stable performance over temperature and high frequency operation which makes it suitable for use in switching power supplies.
• Small size and light weight, thus reducing power loss in integrated circuits.

Conclusion
FDB3860 is a low-voltage driving PMOS power MOSFET, and it is widely used in many industries. It offers low on-state resistance, high switching speed, low threshold voltage, low drain-to-source leakage current, good static and dynamic characteristics, high breakdown voltage and high frequency operation.
