PCF8883 switch equivalent, capacitive touch/proximity switch.
I I I I I I I I I I I I I I Dynamic proximity switch Digital processing method Adjustable sensitivity, can be made very high Adjustable response time Wide input capacitan.
(IDD = 3 µA, typical) Output configurable as push-button, toggle, or pulse Wide voltage operating range (VDD = 3 V to 9 V.
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) ar.
