- The response time max about 60mS at fast mode, 220mS at low power mode @VDD=3V ƒ
- Sensitivity can adjust by the capacitance(0~50pF) outside ƒ
- Have two kinds of sampling length by pad option(SLRFTB pin) ƒ
- Stable touching detection of human body for replacing traditional direct switch key ƒ
- Provides Fast mode and Low Power mode selection by pad option(LPMB pin) ƒ
- Provides direct mode、toggle mode by pad option(TOG pin)
- Open drain mode by bonding option, OPDO pin is open drain output, Q pin is CMOS output ƒ
- All output modes can be selected active high or active low by pad option(AHLB pin) ƒ
- Have the maximum on time 100sec by pad option(MOTB pin) ƒ
- Have external power on reset pin(RST pin) ƒ
- After power-on have about 0.5sec stable-time, during the time do not touch the key pad, And the function is disabled ƒ
- Auto calibration for life
- Re-calibration period is about 4.0sec, when key has not be touched
