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.<\/p>\n

It determines finger proximity by detecting the change in charge level between the operator's finger and the touch pad electrode. With ultra-low 1.5 uA standby current at 3V, it is optimized for battery-powered applications. The sensitivity is adjustable through an external capacitor (Cs, 0-50 pF), and the output mode is configurable via the STG and SLH pins: direct (momentary) or toggle (latching), active-high or active-low. The built-in LDO ensures stable operation across the wide 2.0V to 5.5V supply range.","working_principle":"The TTP223-BA6 operates using charge detection technology. An internal oscillator charges and discharges the sense electrode through the SO pin. When a finger approaches the touch pad, the additional capacitance changes the charge\/discharge timing, which is detected by the internal comparator. The STG pin selects between direct mode (output follows touch state, like a momentary button) and toggle mode (output toggles on each touch, like a latching switch). The SLH pin selects the active output level (high or low when touched). In low-power mode, the device periodically samples the sense electrode and returns to sleep, achieving 1.5 uA average current. Auto-calibration occurs approximately every 4 seconds during idle and 16 seconds after a touch release, compensating for environmental drift.","pin_description":"
