TTP233D-QA6
Model
TTP233D-QA6
Package
SOT23-6
Product overview
Taiwan Tongtai TTP233D-QA6_ comes with reset built-in LDO one-touch IC
Detailed description

Overview


TTP233D-QA6 TonTouchTM is a one-button touch detection chip. This touch detection chip has a built-in voltage regulator circuit to provide a stable voltage for the touch sensing circuit. The stable touch detection effect can meet the needs of different applications.


This touch detection chip is designed to replace traditional buttons. The size of the touch detection PAD can be set according to different sensitivity.


Within a reasonable range, low power consumption and wide operating voltage are characteristics of this touch chip in DC or AC applications.

Special feature


Working voltage 2.4V ~ 5.5V


Built-in voltage regulator circuit provides stable voltage for touch detection circuit


Built-in low voltage reset (LVR) function


Working current @VDD=3V, no load


Typical value in low power mode 2.5uA?1?0max 5uA


The longest response time is approximately 220ms @VDD=3V


Sensitivity can be adjusted by an external capacitor (1~50pF)


Stable human touch detection replaces traditional pushbutton switches


Provide low power mode


Provide output mode selection (TOG pin)


Choice of direct output or toggle output


Provides a maximum output time of approximately 16 seconds (±50%)


Q pin is a CMOS output, which can be selected by (AHLB pin) to select high level output or low level output.


There is a stable time of about 0.5 seconds after power-on. Do not touch the detection point during this period. All functions are prohibited at this time.


Automatic calibration function


The reference value is refreshed every 1 second within 8 seconds after power-on. If there is a touch button within 8 seconds after power-on or 8 seconds, it still does not touch.


Press the button to switch the recalibration cycle to 4 seconds


Application range


Various consumer products


Replace button button
