Overview

Product Highlight

  • Type: Capacitive
  • Supply Voltage: 2.7 to 3.6 V

The SX8638 is an ultra low power, fully integrated 8-channel solution for capacitive touch-buttons and slider with proximity detection applications. Unlike many capacitive touch solutions

The SX8638 features dedicated capacitive sense inputs (that requires no external components) in addition to 8 general purpose I/O ports (GPIO). Each GPIO is typically configured as LED driver with independentPWM source for enhanced lighting control such asintensity and fading.

The SX8638 includes a capacitive 10 bit ADC analog interface with automatic compensation up to 100pF.The high resolution capacitive sensing supports a wide variety of touch pad sizes and shapes and allows capacitive buttons to be created using thick overlay materials (up to 5mm) for an extremely robust and ESD immune system design.

Features:

  • Proximity capacitive touch sensor platform for button, slider and wheel control applications
  • Proximity sensing up to 10cm
  • Eight independent, 256-step LED drivers with auto-lightening mode and individual intensity and fading control
  • High-resolution capacitive sensing (able to sense through overlay materials >5mm thick)
  • Low power consumption optimized for battery-powered applications: 220µA (typ) in active mode; 80µA (typ) in doze mode; 8µA (typ) in sleep mode
  • Auto offset compensation eliminates false triggers due to environmental factors
  • Zero external components required for sensor input
  • Multi-time in-field programmable firmware parameters for ultimate flexibility

Applications:

  • Automotive: Audio/Video Module
  • Cell Phone/Smart Phone: Touchscreen Controller
  • Digital Camera: Touchscreen Controller
  • HDTV: Control Buttons
  • Laser Printer: Touchscreen Controller
  • MP3 Player: Touchscreen Controller
  • Set Top Box: Touch Pads
  • White Goods: Control Buttons
