General Description
The CAP1188, which incorporates RightTouch® tech-
nology, is a multiple channel Capacitive Touch sensor
with multiple power LED drivers. It contains eight (8)
individual capacitive touch sensor inputs with program-
mable sensitivity for use in touch sensor applications.
Each sensor input automatically recalibrates to com-
pensate for gradual environmental changes.
The CAP1188 also contains eight (8) LED drivers that
offer full-on / off, variable rate blinking, dimness con-
trols, and breathing. Each of the LED drivers may be
linked to one of the sensor inputs to be actuated when
a touch is detected. As well, each LED driver may be
individually controlled via a host controller.
The CAP1188 includes Multiple Pattern Touch recogni-
tion that allows the user to select a specific set of but-
tons to be touched simultaneously. If this pattern is
detected, then a status bit is set and an interrupt gen-
erated.
Additionally, the CAP1188 includes circuitry and sup-
port for enhanced sensor proximity detection.
The CAP1188 offers multiple power states operating at
low quiescent currents. In the Standby state of opera-
tion, one or more capacitive touch sensor inputs are
active and all LEDs may be used. If a touch is detected,
it will wake the system using the WAKE/SPI_MOSI pin.
Deep Sleep is the lowest power state available, draw-
ing 5uA (typical) of current. In this state, no sensor
inputs are active. Driving the WAKE/SPI_MOSI pin or
communications will wake the device.
