TTP233D

1 key Touch Pad Detector IC TTP233D Outline z The TTP233D TonTouchTM is a touch pad detector IC which offers 1 touch key. The device built-in regulator for touch sensor. Stable sensing method can cover diversity conditions. The touching detection IC is designed for replacing traditional direct button key with diverse pad size. Low power consumption and wide operating voltage are the contact key features for DC or AC application. Characteristic z Operating voltage 2.4V ~ 5.5V z Built-in regulator for touch sensor z Built-in low voltage reset (LVR) function z Operating current, @VDD=3V no load At low power mode typical 2.5uA, maximum 5uA At fast mode typical 5uA, maximum 10uA z The response time max about 60mS at fast mode, 220mS at low power mode @VDD=3V z Sensitivity can adjust by the capacitance（1~50pF）outside z Stable touching detection of human body for replacing traditional direct switch key z Provides Fast mode and Low Power mode selection by pad option (LPMB pin) z Provides normal mode and delay-off mode selection by pad option (DLYB pin) z Provides output type selection by pad option (TOG pin) Direct output or toggle output selection on normal mode Delay-off mode-1 or mode-2 selection on delay-off mode z Provides maximum on time and delay-off time selection by pad option (MOTA, MOTB pin) z Q pin is CMOS output can be selected active high or active low by pad option (AHLB pin) OPDO that has no diode protection, active low z After power-on have about 0.5sec stable-time...
