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.
Features
- 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.
