Stable sensing method can cover diversity conditions.

Preliminary TTP224N-CO8 TonTouchTM 2 KEY TOUCH PAD DETECTOR IC GENERAL.

Operating voltage 2.4V~5.5V.
Built-in regulator.
Operating current, @VDD=3V no load At low power mode typical 2uA, At fast mode typical 6.5uA.
@VDD=3V operating voltage : The response time about 60mS at fast mode,160mS at low power mode.
Sensitivity can adjust by the capacitance(0~50pF) outside for each touch pad.
Provides direct mode or toggle mode、active high or active low by pad option (TOG/AHLB pin).
After power-on have about 0.5sec st.
