نظرة عامة على المنتج
The TTP223-BA6 is a single-key capacitive touch pad detector IC using charge detection technology. Operating from 2.0V to 5.5V with ultra-low 1.5 uA standby current, it replaces mechanical push-buttons with sealed touch pads. Sensitivity is adjustable via external capacitor (0-50pF), and output mode (direct or toggle) is configurable by pin strapping. Housed in a SOT-23-6 package.
