Interface - Sensor, Capacitive Touch

QT310-IS is a capacitive touch field effect transistor research and development of high-performance and high-degree of integration, using CMOS process and low power consumption RF technology to achieve fast response and high precision of self-launching type trigger switch. It can be applied to interface with smart phone, tablet and notebook, projection, light control, guidance system and other operation products with capacitive touch.

This product has advanced hardware and software design, which is convenient for customers to use rapidly. With unique fast processing speed and high reliability, the driver IC can recognize user\'s action on the input surface and output PWM signal. In addition, the IC can be integrated into the main circuit, which can be used as switch to control various working status in the main circuit.

The working principle of QT310-IS is based on RF self-launch technology. When a finger slightly touches the touch surface to form a certain capacitor, an oscillating current is generated, which resonates with the oscillator in the QT310-IS to increase the current in the oscillator circuit. The amplitude of the oscillation increases exponentially, and finally the sensing system recognizes it. After the touch is released, the oscillator stops, and the circuit returns to the original normal state.

QT310-IS is widely used in the fields of low pressure input devices and field effect transistor interface. It can be used in mobile phones, wearable products, consumer electronics, industrial control, home appliances, point of sale devices and other fields. At the same time, it can make many products with human-computer interaction, such as human-computer interaction box, industrial versions of ultrasonic probe and cold storage type identification box.

In the products with QT310-IS, its integrated fast control and new touch screen control through the built-in touch screen function, based on the FFT algorithm, can capture the frequency peak of the surface stimulation, can get a faster reaction time, and then realize its application functions. In addition, the device can detect the Hall current and can measure the displacement of the moving object.

In addition, the capacitance sensor QT310-IS also has excellent performance in power consumption. Compared with traditional resistive touch panels and other capacitance sensors, it has significant energy savings. A large number of tests and simulations, under the premise of meeting the performance requirements, can achieve the lowest power, and reduce the use cycle of the equipment and increase the service life.

Finally, QT310-IS is an ideal platform for capacitive touch. At present, it has been widely used in different application fields, such as wearable devices and automotive control systems. By using this product, it can provide precise control, low power consumption, reliable operation and high cost performance, making the product design and development more systematic and professional
