Touch controller supports three pads

18 March 2009 Switches, Relays & Keypads

Touch sensors have become increasingly popular as more consumer, industrial and automotive designs include touch panels to provide simpler, more reliable user interfaces. Freescale is meeting the demand for touch-sensitive control with the introduction of an ultra low-power touch controller for two- and three-pad touch-sensing applications.

The MPR031 proximity capacitive touch sensor controller is designed to simplify the development of a wide range of touch-sensing applications, such as appliance controls, games, patient monitoring systems, remote controls, PC peripherals, webcams, vehicle and garage key fobs, dimmer switches and security systems.

The new device supports communication via the inter-integrated circuit protocol (I²C). Offering exceptional sensitivity and a specialised feature set, the sensor controllers can accommodate a wide range of system implementations. To simplify the design of touch-based applications, the sensor controllers can be used as drop-in replacements for mechanical devices or switches.

Also available are several kits to help reduce implementation development cycle time.
