PCA8886 Dual channel capacitive proximity switch with auto-calibration and large voltage operating range Rev. 3 14 March 2014 Product data sheet 1. General description The PCA8886 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. Changes in the static capacitance (as opposed to dynamic capacitance changes) are automatically compensated using continuous auto-calibration. Remote sensing plates 1 (for example, conductive foil) can be connected directly to the IC or remotely using a coaxial cable. 2. Features and benefits Dynamic proximity switch Digital processing method Automatic calibration Adjustable sensitivity, can be made very high Adjustable response time Wide input capacitance range (10 pF to 60 pF) 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) Output configurable as push-button, toggle, or pulse Wide voltage operating range (V = 3 V to 9 V) DD Designed for battery powered applications (I = 6 A, typical) DD Large temperature operating range (T = 40 C to +85 C) amb AEC-Q100 compliant for automotive applications Available in TSSOP16 3. Applications Proximity detection Proximity sensing in Door locks and grips Portable entertainment units Computing tablets Switch for medical applications Dashboard: switch to toggle menus and resetting trip counter Switch for use in explosive environments 1.
