CAPSENSE™ Express

CAPSENSE™ Express with SmartSense auto-tuning takes the guesswork out of touch-sensing design

anchor

Overview

Infineon's CAPSENSE™ Express solutions make button replacement easy by eliminating unnecessary software tools, firmware development, device programming, and system tuning. This reduces time-to-market and eliminates the learning curve for designers who are new to capacitive touch-sensing interfaces.

Key Features

  • Ten capacitive sensing buttons
  • Slider segments
  • I2C
  • Voltage range: 2.4 V to 5.25 V
  • 1.5 mA active, 4 µA deep sleep

About

About CAPSENSE™ Express

Infineon offers the broadest portfolio of capacitive touch-sensing products on the market. Its CAPSENSE™ Express MBR family of capacitive touch-sensing controllers is designed for a wide range of applications, with broad operating ranges, strong immunity to RF and AC noise, and the ability to operate at very low power levels.

Advanced touch-sensing solution

In a typical CAPSENSE™ application, there can be significant variation in baseline signal counts due to variability in environmental and noise conditions. Infineon’s revolutionary SmartSense auto-tuning technology, built into CAPSENSE™ Express, establishes, monitors, and maintains the requisite signal-to-noise ratio (SNR) levels for optimal CAPSENSE™ performance. Further, in moving from the prototype stage to mass production, manufacturing variations in PCB and/or overlay material can affect the parasitic or intrinsic capacitance of the system.

SmartSense auto-tuning automatically detects the sensor capacitance threshold level and dynamically optimizes system performance.

The CAPSENSE™ Express family makes the most of Infineon’s broad technology portfolio and years of user-interface know-how so designers can focus on end product development and timely market introductions.
