TTP223-BA6 контролер датчика дотику SOT23-6

Контролер Маркування: 223B Корпус: SOT-23-6 1 key touch pad detector ic Технічні параметри: Operating voltage 2.0 V~5.5 V Operating current @VDD=3V, no load At low power mode typical 1.5 uA, maximum 3.0 uA The response time max 220mS at low power mode @VDD=3V Sensitivity can adjust by the capacitance(0~50pF) outside Stable touching detection of human body for replacing traditional direct key switch Provides Low Power mode Provides direct mode、toggle mode by pad option(TOG pin) Q pin is CMOS output All output modes can be selected active high active or low by pad option(AHLB pin) After power-on have about 0.5 sec stable-time during the time do not touch the key pad, And the function is disabled Auto calibration for life At low power mode the re-calibration period is about 4.0 sec normally, Key When detected touch and released touch, the auto re-calibration will be redoing after about 16sec from key releasing (Дивіться даташит в специфікаціях)
