Microchip expands MTCH10x mTouch capacitive sensing portfolio
In a hardware-only configuration, these 2, 5 and 8-channel controllers replace mechanical buttons with a simple digital output, making it easy to add proximity and touch detection to any application that is constrained by size, power or cost. To achieve high reliability and more sensitive touch performance, including operation through a glove, the MTCH102-5-8 capacitive touch controllers come with advanced multi-stage noise filtering algorithms.
The MTCH102-5-8 controllers support a wide range of touch-sensor shapes and sizes, feature automatic compensation for environmental conditions, and provide reliable operation in the presence of water. Moreover, active guarding increases proximity-sensing sensitivity and makes the electronic design robust, even with long board traces to the touch sensors. The two-channel MTCH102 version comes in a MSOP or uDFN package, the five-channel version in a QFN or TSSOP package, and the eight-channel capacitive touch controller comes in a uQFN or SSOP package. The devices are supported by the company’s compact DM160229 demonstration board.
