Microchip Debuts MTCH65X [Health & Beauty Close - Up]


(Health & Beauty Close - Up Via Acquire Media NewsEdge) Microchip Technology reported a new addition to its Human Interface Input Sensing Solutions portfolio with a standalone integrated high-voltage line driver to increase Signal-to-Noise Ratio for advanced projected-capacitive touch performance-the MTCH65X.



According to a release from the company, the MTCH652 features an integrated boost converter and can interface to any touch controller via SPI to drive up to 19 Transmit channels at selectable voltages up to 18V to increase the SNR in projected capacitive touch systems. The improved SNR increases the robustness of the system in noisy environments, allows thicker cover lenses, and reduces the number of samples and time required by the touch controller to scan large displays. These capabilities are especially important in demanding environments such as white goods, automotive, PC Peripherals and industrial controls markets, among others.

"Microchip's new high-voltage driver MTCH652 provides the industry with a simple high-voltage boost solution that can improve robustness and increase the sensor sizes for today's touch controllers," said Fanie Duvenhage, director of Microchip's Human- Machine Interface Division. "The wide range of input and output voltages supported combined with the ability to daisy chain the MTCH65X devices give our customers more flexibility in their designs." "The addition of Microchip's MTCH652 to our projected-capacitive electronics solution resulted in a more robust design that supports larger size displays up to 24" and facilitated passing 10V/m for Radiated Susceptibility (RS) testing and 10Vrms for Conducted Susceptibility (CS) testing (per IEC61000-4-3 Level 3 and IEC61000- 4-6 Level 3)," said Lillian Chao, president of Apex Material Technology Corp. (AMT). "In addition, using the MTCH652 helped AMT achieve advanced features such as water immunity and gloved input. Also, AMT was able to easily integrate multiple MTCH652 chips to support larger designs."
