1 Keys Feel Board Detector IC TTP223E-BA6 SOT23-6 SMD Feel Sensor Control Chips

Description: 

1. Operating voltage 2.0V~5.5V
2. Operating current ,@VDD=3V no load at low power mode typical 2.0uA , maximum 4.0uA
3. The response time max about 220mS at low power mode @VDD=3V
4. Sensitivity can adjust by the capacitance(1~50pF) outside
5. Stable feeling detection of human body for replacing traditional direct switch key
6. Provides low power mode
7. Provides direct output selection by pin option(TOG pin)
8. Q pin is CMOS output can be selected active high or active low by pin option (AHLB pin)
9. After power-on have about 0.5sec stable-time , during the time do not feel the key pad , and the function is disabled
10. Auto calibration for life
the re-calibration period is about 1sec within 8 sec after power-on.When key has been feeled within 8 sec or key has not been feeled more than 8 sec after power-on , then the re-calibration period change to 4 sec

Package included: (According to your choice)
