Product Description:

1. General description
    The integrated circuit PCF8883 is a capacitive touch and proximity switch that uses a patented (EDISEN) digital method to detect a change in capacitance on a remote sensing plate. Changes in the static capacitance (as opposed to dynamic capacitance changes) are automatically compensated using continuous auto-calibration. Remote sensing plates (e.g. conductive foil) can be connected directly to the IC1 or remotely using a coaxial cable.
 
2. Features and benefits

•  Dynamic proximity switch
•  Digital processing method
•  Adjustable sensitivity, can be made very high
•  Adjustable response time
•  Wide input capacitance range (10 pF to 60 pF)
•  Automatic calibration
•  A large distance (several meters) between the sensing plate and the IC is possible
•  Open-drain output (P-type MOSFET, external load between pin and ground)
•  Designed for battery powered applications (I_DD = 3A, typical)
•  Output configurable as push-button, toggle, or pulse
•  Wide voltage operating range (V_DD = 3 V to 9 V)
•  Large temperature operating range (T_amb =-40 to +85)
•  Internal voltage regulator
•  Available in SOIC8 and wafer level chip-size package (CSP)

•  Proximity detection
•  Proximity sensing in

•  Switch for medical applications
•  Switch for use in explosive environments
•  Vandal proof switches
•  Transportation: Switches in or underupholstery, leather, handles, mats, and glass
•  Buildings: switch in or under carpets, glass, or tiles
•  Sanitary applications: use of standard metal sanitary parts (e.g. tap) as switch
•  Hermetically sealed keys on a keyboard
