FDC6302P is an array of N-channel MOSFETs (metal-oxide semiconductor field-effect transistors) packaged in a single integrated circuit. It provides up to eleven MOSFETs in a small TSSOP package, making it one of the most popular low-cost surface-mount options for PCB (Printed Circuit Board) assemblies. The FDC6302P is typically used as a switch to bypass signals in applications such as audio amplifiers, computers and cellular phones. This article will discuss the application fields and working principle of FDC6302P.

The FDC6302P MOSFET array is a perfect choice for controlling high-power circuits due to its wide voltage range, up to 60V on the drain to source. Its high-current capability and wide frequency range, up to a few hundred megahertz, make it ideal for switching high-frequency signals or for controlling stepped motors. This means that the FDC6302P is ideal for use in applications such as power converters and motor controllers, as well as in DC/DC converters and isolated AC/DC supplies.

One popular application of the FDC6302P is as a low-side switch in a Class-D amplifier. Here it can be used to bypass signals, allowing the user to switch between a direct signal and an amplified one. It is also used as a high-side switch in motor control applications, as its low on-resistance provides good electrical isolation between the control inputs and the output. This is especially important for applications such as automotive systems and industrial machinery.

The FDC6302P’s operation is based on the principle of depletion mode MOSFETs. In a depletion mode MOSFET, the gate-source voltage determines the drain-source current, and the gate-source voltage must be greater than the threshold voltage in order for the MOSFET to be turned on or “active”. The FDC6302P also includes two built-in protection features, such as over-voltage protection and thermal shutdown. This is important when dealing with high-power, high-current circuits, as it reduces the risk of damaging the device.

In summary, the FDC6302P is an ideal choice for controlling high-power circuits and switching high-frequency signals. It is widely used in applications such as audio amplifiers, motor controllers, and power converters. Its low on-resistance and wide voltage range make it an excellent choice for low-side and high-side switching circuits. Its built-in protective features also make it a safe choice for high-power applications.
