key The touching detection IC is designed for replacing traditional direct button key with diverse pad

size Low power consumption and wide operating voltage are the contact key features for DC or AC

FEATURES

Operating voltage 2.0V~5.5V

Operating current @VDD=3V, no load

At low power mode typical 1.5uA, maximum 3.0uA

The response time max 220mS at low power mode @VDD=3V

Sensitivity can adjust by the capacitance(0~50pF) outside

Stable touching detection of human body for replacing traditional direct switch key

Provides Low Power mode

(Provides direct mode、toggle mode by pad option(TOG pin

Q pin is CMOS output

(All output modes can be selected active high or active low by pad option(AHLB pin

After power-on have about 0.5sec stable-time, during the time do not touch the key pad

And the function is disabled

Auto calibration for life
