Microchip announces the expansion of its MTCH10x mTouch® sensing portfolio with the MTCH102-5-8 capacitive touch controllers. In an all-hardware configuration, these 2, 5, and 8-channel controllers replace mechanical buttons with a single digital output MTCH102-5-8 drivers incorporate advanced multi-stage noise filtering algorithms. They support a wide range of touch sensor shapes and sizes, offer automatic compensation for environmental conditions, and ensure reliable operation in the presence of water. Furthermore, active protection enhances proximity sensing sensitivity and enables a robust electronic design, even with long traces on the board to the touch sensors.
The MTCH102-5-8 low-power touch controllers create robust, ready-to-use applications that cover the rapidly growing capacitive human-to-human interfaces for industrial applications such as lighting switches; home automation products such as security control panels, thermostats, and lighting controls; office equipment such as printers, copiers, and fax machines; and consumer products such as toys and household appliances; plus applications in other markets.
To facilitate the evaluation and configuration of capacitive touch interfaces, the MTCH102-5-8 is supported by Microchip’s new DM160229 compact demo board, priced at $29.95 and available starting in November.
The new MTCH102 mTouch low-power, two-channel capacitive sensing controller is available now in MSOP or uDFN packages for sampling or volume production. The MTCH105 low-power, five-channel capacitive touch controller is available now in QFN or TSSOP packages for sampling or volume production. The MTCH108 low-power, eight-channel capacitive touch controller is also available now in uQFN or SSOP packages for sampling and volume production.
