PCA8885TS
Capacitive 8-channel touch and proximity sensor with auto-calibration and very low power consumption
1. General descriptionThe 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. Remote sensing plates
(for example, conductive foils) can be connected to the IC1 using coaxial cable. The eight
input channels operate independently of each other. There is also a built-in option for a
matrix arrangement of the sensors: interrupt generation only when two channels are
activated simultaneously, suppression of additional channel outputs when two channels
are already active.
2. Features and benefits 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 modesI2 C Fast-mode Plus (Fm+) compatible interface Two I2 C-bus addresses Cascading of two ICs possible Interrupt signaling over I2 C-bus Interrupt output Large voltage operating range (VDD = 2.5V to 5.5V) Sleep mode (IDD < 100 nA) Low-power battery operation possible (IDD ~10 A) Operating temperature range (Tamb = 40 C to +85 C)

7.2 Pin description[1] The internal regulated supply voltage output must be decoupled with a decoupling capacitor to VSS.
[2] If a channel is not used, the appropriate sensor input line has to be left open, the corresponding CPCn has
to be connected to VSS and the channel should be disabled in the MASK register (see Table 11 on
page 15).
[3] The die paddle (exposed pad) is connected to VSS and should be electrically isolated.
[4] Used to address two devices, for example: low address 3Ah, high address 3Bh.
Table 4. Pin descriptionInput or input/output pins must always be at a defined level (VSS or VDD) unless otherwise specified.
