1 key Touch Pad Detector IC Outline z The TTP233D-HA6 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 z The response time max about 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 Low Power mode z Provides direct output or toggle output selection by pin option (TOG pin) z Q pin is CMOS output can be selected active high or active low by pin option (AHLB pin) z Have the maximum on time about 16 sec(±50%) z After power-on have about 0.5sec stable-time, during the time do not touch the key pad, and the function is disabled z Auto calibration for life The re-calibration period is about 1 sec within 8 sec after power-on. When key has been touched within 8 sec or key has not been touched more than 8 sec after power-on, then the re-calibration period change to 4 sec Applications z Wide consumer products z Button key replacement TTP233
