CAP1188中文资料Touch Sensing/Turnkey Products数据手册Microchip规格书

描述 Description

The CAP1188 is a turnkey capacitive touch controller providing a wide variety of  button and proximity functionality, and making it easy for designers to add aesthetically pleasing, low-cost and robust touch interfaces. The CAP1188 also contains 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.
