General description

The integrated circuit PCF8883 is a capacitive 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.

Features

I Dynamic proximity switch

I Digital processing method

I Adjustable sensitivity, can be made very high

I Adjustable response time

I Wide input capacitance range (10 pF to 60 pF)

I Automatic calibration

I A large distance (several meters) between the sensing plate and the IC is possible

I Open-drain output (P-type MOSFET, external load between pin and ground)

I Designed for battery powered applications (IDD = 3 µA, typical)

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

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

I Large temperature operating range (Tamb = −40 °C to +85 °C)

I Internal voltage regulator

I Available in SOIC8 (other packages available on request for larger quantities)
