PCA8885
Overview
The integrated circuit PCA8885 is a capacitive 8-channel touch and proximity sensor that uses a patented (EDISEN) method to detect a change in capacitance on remote sensing plates. Changes in the static capacitances (as opposed to dynamic capacitance changes) are automatically compensated using continuous auto-calibration.
- AEC-Q100 compliant for automotive applications
- Dynamic touch and proximity sensor with 8 sensor channels
- Support for matrix arrangement of sensors
- Sensing plates can be connected remotely
- Adjustable response time
- Adjustable sensitivity; Continuous auto-calibration; Digital processing method; Can cope with up to 6 mm of acrylic glass
- Direct and latching switch modes
- I2C Fast-mode Plus (Fm+) compatible interface; Two I2C-bus addresses; Cascading of two ICs possible; Interrupt signaling over I2C-bus
- Interrupt output
- Large voltage operating range (VDD = 2.5 V to 5.5 V)
