Note:
Description
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 enhances proximity detection when used with battery (DC)
applications.
