This datasheet introduces the basic information of NXP PCA8886 sensor. It is a low power dual channel capacitive proximity switch that uses a patented EDISEN digital method to detect a change in capacitance on remote sensing plates. Static capacitance (i.e. non-dynamic capacitance changes) are automatically compensated by continuous auto-calibration. Remote sensing plates (e.g. conductive foil) can be connected directly to the IC1 or remotely using a coaxial cable.
The PCA8886 is a low power dual channel capacitive proximity switch that uses a patented digital method to detect changes in capacitance on remote sensing plates. It features continuous auto-calibration to compensate for static capacitance changes, allowing remote sensing plates to be connected directly to the IC or remotely via a coaxial cable.
Key features include adjustable sensitivity and response time, a wide input capacitance range of 10 pF to 60 pF, and a large voltage operating range of 3 V to 9 V. The device is designed for battery-powered applications with a typical current consumption of 6 µA and is AEC-Q100 compliant for automotive use.
