8 Channel Capacitive Touch Sensor with 8 LED Drivers
The CAP1088 is a multiple channel Capacitive Touch sensor with multiple power LED drivers. It c
ontains eight (8) individual Capacitive Touch sensor inputs with programmable sensitivity for use in touch sensor applications. Each sensor automatically recalibrates to compensate for gradual environmental changes.
The CAP1088 also contains eight (8) LED drivers that offer full-on / off, variable rate blinking, dimness controls, and breathing. Each of the LED drivers may be linked to one of the sensors to be actuated when a touch is detected.
Aswell, each LED driver may be individually controlled via a host controller.
The CAP1088 offers multiple power states operating at low quiescent currents.
During the Standby mode of operation, one or more Capacitive Touch Sensors are active and all LEDs may be used. If a touch is detected, then it will wake the system using the WAKE/
SPI_MOSI
pin.
