The LDS6108NQGI is an integrated capacitive touch controller. It offers a cost-effective, high-integration, low-power, high-performance and high-stability design.

Application Field

The integrated touch controller chip of LDS6108NQGI is widely used in LCD displays, non-metallic capacitive touch panels, digital photo frames, cash registers, ATMs, vending machines, remote control devices, digital toys, industrial computers and other TP-related applications.

Working Principle

The LDS6108NQGI capacitive touch controller utilizes a patented capacitive detection circuit, which can accurately monitor the changes of human body capacitance. When the touch panel is touched, the capacitance value of the touched area changes, and the LDS6108NQGI touch controller can detect the change of the capacitance value, and then convert the change into an electronic signal. The signal is then sent to the microprocessor for further processing.

This capacitive touch controller is based on a self-calibrating Electro-Static Capacitance (ESC) technology. The calibration process is managed by the built-in software, which adjusts the capacitance detection range and cancels the interference of the environment. In addition, it is integrated with an innovative digital adjustment technique, which can adjust the gain of the detection signal, which helps to improve the accuracy and stability of the controller.

The LDS6108NQGI works reliably under extreme conditions, with additional electrostatic protection and wide temperature range (-20°C to +85°C) support. In addition, it offers accurate touch sensing and detection, up to 1.8mm thickness of the substrate, and offers low power consumption to the touch device, with an integrated power management unit (PMU) to reduce power consumption and noise.

The LDS6108NQGI can also support up to 2,048 sensors for multi-touch operation and up to 128 channels for single point. It comes with an integrated auto switch, which can automatically change between low-power and high-sensitivity modes. It also has an integrated gesture recognition engine, which can recognize predefined gestures and operations made on the touch panel.

The LDS6108NQGI is an ideal solution for applications that require high accuracy, high performance and reliable operation in a miniaturized form factor. It maintains high accuracy and stability even in environments with varying temperatures, as well as under different interferences. Its low cost and wide range of features make it an ideal solution for a wide range of consumer, commercial and industrial touch panel applications.
