,Introduction
The FDC2114RGHT is a touch controller specifically designed for the automotive industry. It is an advanced ASIC (Application Specific Integrated Circuit) device manufactured especially for the needs of car users, offering unparalleled accuracy and convenience. With its wide range of input sources and specialized design, it is ideal for touch sensing applications that require a high degree of accuracy and reliability.
Application Field and Working Principle
The FDC2114RGHT touch controller is designed to be used in a wide variety of automotive applications. It is designed for high accuracy and reliability, enabling precise control of the vehicle’s user interface. The controller is compatible with capacitive touch screens, track pads, and other similar touch systems, making it suitable for a wide range of applications. The device supports two kinds of capacitive touch technology: mutual capacitance and self-capacitance. Usual applications are cruise control and steering wheel controls, lighting control, airbag system, rearview mirror control, seat adjustment, multimedia control, climate control, and infotainment systems.
Mutual Capacitance Technology
The FDC2114RGHT utilizes mutual capacitance technology, meaning that it can detect the location of a touch input on the capacitive touch screen. Mutual capacitance technology works by applying an alternating electric current (AC) to two electrodes placed on the capacitive touch screen. When a finger touches the screen, an additional electric field is generated and the controller can measure the amount of capacitance between the two electrodes and calculate where the touch occurred. This technology provides a high degree of accuracy and reliability and is often used in automotive touch input systems.
Self-Capacitance Technology
The FDC2114RGHT also supports self-capacitance technology. Self-capacitance technology works by measuring the amount of electric charge stored on a single electrode placed on the capacitive touch screen. When a finger touches the screen, the electric charge on the electrode changes and the controller can detect this change and calculate where the touch occurred. This technology provides a less accurate and less reliable method of measuring touch input, and is often used in automobiles with standard capacitive touch screens.
Conclusion
The FDC2114RGHT is an Application Specific Integrated Circuit (ASIC) device designed specifically for the automotive industry. It is an advanced touch controller that supports both mutual capacitance and self-capacitance technologies, making it suitable for a wide range of automotive applications. With its high accuracy and reliability, it is an ideal solution for touch sensing applications that require a high degree of precision and control.
