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 (IDD = 3 A, typical)

 Output configurable as push-button, toggle, or pulse

 Wide voltage operating range (VDD = 3 V to 9 V)

 Large temperature operating range (Tamb = 40 C to +85 C)

 Internal voltage regulator

 Available in SOIC8 and wafer level chip-size package

3.

Applications

 Proximity detection

 Proximity sensing in

 Mobile phones

 Portable entertainment units

 Switch for medical applications

 Switch for use in explosive environments

 Vandal proof switches

 Transportation: Switches in or under upholstery, leather, handles, mats, and glass
