TTP223E-BA6 SOT23-6 SMD Touch Sensor Chip

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
