PCA8886
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
(for example, 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
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 (VDD = 3 V to 9 V)
Designed for battery powered applications (IDD = 6 A, typical)
Large temperature operating range (Tamb = 40 C to +85 C)
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
