Single-button touch chip IC Capacitive touch chip IC Single-button touch switch chip IC

It is the touch panel detector integrated circuit that provides the touch keys. The device has built-in regulator touch sensor. Stable sensing methods can cover diverse conditions. The
Touch detection design replaces traditional direct buttons with diversified keypad sizes.
Low power consumption and wide operating voltage are key features for DC or AC contact
applications.

A stable human touch detection replaces the traditional direct transfer switch
Provides low Power mode
Provides direct output or output switching selection pad option (Cloth pin)
Ask pin output can choose active high pad or active low option (B pin)
Maximum time in seconds< br/> Do not touch the keypad during the stabilization time of power on,
and the function is disabled
Auto Calibration
The b period is approximately 2 seconds after power-on. . When the key is
touched within seconds or the key is not touched for more than seconds after powering on, then
b the time is changed to seconds.
Applications
Broad range of consumer products
Button key replacement
