Base chip for Arduino touch sensors. Can be used as a physical contact detector, low energy consumption. Technical data: Operating voltage 2.0V~5.5V Low power mode Operating current @VDD=3V no load at low power mode typical 2.0uA , maximum 4.0uA Response time max 220ms at low power mode @VDD=3V Sensitivity can be adjusted by providing outer capacitance 1~50pF Provides direct output selection by pin option(TOG pin) Q pin is CMOS output can be selected active high or active low by pin option (AHLB pin) After power-on approx. 0.5sec is required for stabilizing Auto calibration. Recalibration time is 1sec within 8 sec after power-on. When touch has been detected within 8 sec or it has not been detected for more than 8 sec after power-on, the re-calibration time changes to 4 sec https://elecena.pl/product/25569138/ttp223e-ba6-sot23-6-smd-touch-sensor-chip 2024-03-12 https://elecena.pl/product/25569138/ttp223e-ba6-sot23-6-smd-touch-sensor-chip 2025-10-29
