The AO8818 is an integrated switch array comprised of 8 complementary FETs in a single package. By leveraging their full complement of features, this device can be used in a wide range of applications, including general purpose switching, display and backlight control, and power management. This article will discuss the AO8818\'s many features and application fields, as well as its working principle.

AO8818 Features and Application Fields

The AO8818 contains eight N-type and eight P-type FETs in a single package. Each has its own gate lead, making it easy to control separate channels from the same package. The FETs can be used in parallel for greater current handling capabilities, or in series for higher voltage switching. The high common-mode rejection ratio of the FETs ensures low noise performance. The low on-resistance of the FETs allows them to control a variety of loads, including LEDs and motors.

Due to these features, the AO8818 is well suited for a variety of applications, including general purpose switching and control, display and backlight control, automotive in-cabin lighting, power management, and more. The AO8818 is easy to use and provides good performance, making it an ideal solution for a wide range of applications.

AO8818 Working Principle

The AO8818 contains eight N-type FETs and eight P-type FETs. When a control voltage is applied to the gate of one of the FETs, current will flow from the drain to the source. Depending on the type of FET, positive or negative current will flow. The on-resistance of the FETs determines how much current can flow when a control voltage is applied.

The wide control voltage range of the AO8818 makes it suitable for a variety of applications. When used in combination with a microcontroller or other control device, the AO8818 can be used for a variety of tasks such as dimming, ON/OFF control, and pulse width modulation.

In addition to its great features, the AO8818 has a wide temperature range and is available in a variety of packages. The AO8818 is also RoHS compliant and requires no external components for proper operation.

Conclusion

The AO8818 is a versatile, easy-to-use integrated switch array that can be used in a variety of applications. Its full complement of features and wide temperature range make it an ideal solution for general purpose switching, display and backlight control, and power management. The AO8818 is RoHS compliant and requires no external components for proper operation.
