Accelerate EMI Qualification of Automotive Touchscreens with New Capacitive Touch Controllers

19.08. 2019 | News

To address electromagnetic interference (EMI) and electromagnetic compatibility (EMC) challenges faced by developers of automotive touchscreens, three new maXTouch® touchscreen controllers and optimization services are now available from Microchip Technology Inc. The TD family of touch controllers features a new differential mutual signal acquisition method that significantly increases the Signal-to-Noise Ratio (SNR). This allows the use of very thick glass or plastic cover lenses and multi-finger thick gloved touch support up to the equivalence of 4.5 mm polymethyl methacrylate (PMMA).

The MXT1067TD, MXT1189TD and MXT1665TD devices add several variants that are cost optimized for nine- to 13-inch automotive touchscreens to Microchip’s portfolio and are complemented by the recently-introduced MXT449TD, MXT641TD, MXT2113TD and MXT2912TD devices supporting up to 20-inch touchscreens (more info).
