CAP1188-1-CP-TR

CAP1188-1-CP-TR incorporates RightTouch® technology, is a multiple channel capacitive touch sensor with multiple power LED driver. It contains eight (8) individual capacitive touch sensor inputs with programmable sensitivity for use in touch sensor applications. Each sensor input automatically recalibrates to compensate for gradual environmental changes. This 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 sensor inputs to be actuated when a touch is detected. As well, each LED driver may be individually controlled via a host controller. This includes multiple pattern touch recognition that allows the user to select a specific set of buttons to be touched simultaneously. applications include desktop and notebook PCs, LCD monitors, consumer electronics, appliances.

• Automatic recalibration, individual thresholds for each button
• Proximity detection, multiple button pattern detection
• Calibrates for parasitic capacitance, analog filtering for system noise sources
• Press and hold feature for volume-like applications
• Multiple communication interfaces, SMBus / I²C compliant interface
• SPI communications, pin selectable communications protocol
• Low power operation, 5uA quiescent current in deep sleep
• 50uA quiescent current in standby (1 sensor input monitored)
• Programmable blink, breathe, and dimness controls
• 24-pin QFN package, operating ambient temperature range from 0 to +85°C (extended commercial)
