• ILI2322: 140 touch channels, supports 32-inch screens; Vtx drive voltage increased to 15V, compatible with both USB and I2C dual interfaces; supports 10mm cover glass penetration and waterproof function, operating temperature -40℃ to 85℃, suitable for home smart TVs or commercial displays.
• ILI2323: 170 touch channels, maximum support for 43-inch screens; increases the number of channels based on ILI2322, adapting to larger gaming screens or conference tablets while maintaining 15V high drive voltage and dual interface design.
• ILI2136: 220 touch channels, single chip supports 65-inch ultra-large screens; Vtx drive voltage upgraded to 30V (industry-leading level), can penetrate 10mm thick cover glass; compatible with USB/I2C interfaces, suitable for 65-inch smart TVs, digital signage, or large industrial control panels, solving the problem of insufficient touch sensitivity on large screens.
ILI25xx Series:
Integrated solutions for full size coverage
This series caters to both medium (15.6-23.8 inches) and small size scenarios, emphasizing high integration and low energy consumption, applied in laptop touchpads, all-in-one machines, and medium industrial control devices. Key models are as follows:
• ILI2511: Highly integrated single-chip capacitive touch controller; supports multi-finger (up to 10 fingers) simultaneous tracking, built-in electromagnetic interference (EMI) technology; suitable for smartphones, tablets, and industrial control devices, balancing precise touch and low power consumption, ideal for products with high interaction experience requirements.
• ILI2520: 65 touch channels, supports 15.6-inch screens; Vtx=15V drive voltage, USB/I2C dual interface, 10mm cover penetration and waterproof function, operating temperature -40℃ to 85℃, suitable for laptop touch screens or medium all-in-one machines.
• ILI2521: 110 touch channels, maximum support for 23.8-inch screens; significantly increases the number of channels compared to ILI2520, suitable for 23.8-inch all-in-one machines or industrial displays, maintaining 15V drive voltage and full environmental adaptability.
ILI27xx Series:
Automotive and industrial-grade selection for harsh environments
This series is AEC-Q100 certified, emphasizing a wide operating temperature range, specifically designed for automotive displays, industrial control, and other harsh environments. Representative model:
• ILI2712: 72 touch channels, supports 12.3-inch screens; AEC-Q100 automotive certification, operating temperature range extended to -40℃ to 105℃ (can withstand high temperature, high humidity, vibration, and other harsh environments); supports 10mm cover penetration and waterproof function, suitable for automotive central control screens, instrument panel touch, or industrial high-temperature scenario devices.
ILI6600A:
Benchmark TDDI product in the automotive safety field
As ILITEK’s flagship model for touch and display driver integration (TDDI), the ILI6600A is designed specifically for automotive displays, compliant with ISO 26262 ASIL B functional safety standards, and features real-time fault detection capabilities to ensure touch reliability during driving.
