STM8T141 Single-channel capacitive sensor for touch or proximity detection with shielded sensing electrode

The STM8T141 is a ProxSense™ single-channel, fully integrated, charge-transfer, capacitive sensor that is designed to replace conventional electromechanical switches in cost-sensitive applications.

The STM8T141 is offered in 8-pin packages and is ideally suited for 1-button applications. It can be configured either in touch or proximity sensing mode for wake-up or backlighting on actuation.

The extremely low current consumption makes it an ideal solution for battery-powered applications.

The device features an internal voltage regulator to enhance detection sensitivity and stability.

The STM8T141 touchpad can sense through almost any dielectric and can thereby contain the electronics in a sealed environment.

The STM8T141 also incorporates the advantages of using a driven shielding capability. This makes it possible to separate the sealed electronics from the sensing electrode. The shield feature enables the designer to protect part of the sensing element from unwanted environmental interference and enhance proximity detection when used with battery (DC) applications.

技术特性
  • Touch or proximity detection (a few centimeters)
  • Built-in driven shield function:
    • Enhance proximity detection
    • Protect sensing electrode from noise interference
  • Ultra-low power modes suitable for battery applications (11 μA in extreme low power mode)
  • On-chip integrated voltage regulator
  • Environment compensation filter
  • User programmable options include:
    • Four detection thresholds
    • Four output modes
    • Four low power modes
    • Reference freeze timeout
  • Minimal external components
