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.
Features
◾ 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
Applications
◾ Consumer electronics
◾ Power-critical and battery applications
– Wake-up on proximity
◾ Home and office appliances
– Find-in-the-dark (FITD) applications using
proximity detection
– Sanitary ware and white goods
◾ Flameproof human interface devices for use in
hazardous environments
