To reduce the risk of fires in the kitchen and also floods in the laundry room, European IEC 60730 and U.S. UL 60730 Class B specifications require safety mechanisms in home appliances, such as ovens, cooktops, washing machines and clothes dryers. Helping designers meet these functional safety requirements in touch screen enabled appliances, Microchip Technology announced its maXTouch® MXT336UD-MAUHA1 capacitive touchscreen controller family — the market’s only touchscreen controllers to offer pre-certified, Class B firmware. The family includes three controllers, the MXT112UD-MAUHA1, the MXT228UD-MAUHA1 and the MXT336UD-MAUHA1, each fulfilling different screen size needs, ranging from 2-to 8-inches.

The Class B certified touch controllers offer unique safety-related features that enable system shut off through an intuitive soft button on a touchscreen, removing the requirement for an external safety certified stop or cancel button and associated microcontroller (more info).
