AOC2802 Application Field and Working Principle

AOC2802 is an advanced 2-input N-channel MOSFET array with many applications, including driving output drivers and buffers, level shifting, or inserting analog switches or logic gates in any digital logic application. This FET array is made of a series of N-channel enhancement-mode MOSFETs, each with a low pinch-off voltage and a low gate threshold. In other words, it is an array of 4 N-channel MOSFETs with a single control button.

AOC2802 MOSFET array works by consolidating four N-channel MOSFET transistors onto one chip, with a common gate voltage input. This replaces four discrete transistors with one single device, reducing overall cost and saving space. The common input allows for a combination of multiple logic states, producing specific functionality based on the arrangement of the transistors and the applied voltages. The arrangement of the transistors allows for a high speed switching rate, with response times of 1 nanosecond, the fastest available. The integrated design also provides an improved level of noise suppression.

The MOSFETs are connected in series, providing transistor level voltage gain with the gate voltage towards the drain and source. This makes the MOSFETs easier to control and operate, translating digital signals into higher voltage levels. A typical application of the MOSFET array is an analog switch, where the sequence of transistors can control gain for custom operation. The wide range of supply voltages ranging from 3 to 16 volts makes the AOC2802 MOSFET array a versatile device able to perform in many different applications.

The saturation characteristics of the AOC2802 MOSFET array is also improved due to its high density, allowing it to be used in high speed circuits and output buffers. This can be seen in the switching characteristics, where if the input voltage increases above the VGS, then the output voltage also increases, allowing for high speed operation, as well as higher current levels. Additionally, the ability to manage PWM signals with great precision and accuracy, thanks to the high speed response times and the fact that the transistors are connected in series, makes this MOSFET array suitable for digital motor control applications.

In conclusion, the AOC2802 MOSFET array is an advanced 2-input logic device with a series of N-channel MOSFETs, providing improved level of noise suppression and high speed switching functionality. With a wide range of supply voltages, low pinch-off voltage, and response times of 1 nanosecond, this FET array is a versatile device for many advanced applications.
