Capacitive Touch Controllers and Proximity Sensing Solutions
As part of the sensing products family, Semtech offers capacitive touch button solutions that enhance the ECO mode present in many green home electronics. Our touch button controllers are integrated with an IR decoder for automatic system wake up, thus minimizing the power consumption while in standby. The circuitry also combines the capacitive sensor with the LED driver to reduce the overall footprint. Some of the various benefits of these touch sensing interfaces include extreme sensitivity, enhanced LED operation, buzzer control for audible feedback, and advanced LED driver for visual feedback. Our capacitive touch controller ICs come in 8- and 12-channel models and support a wide range of button, slider and touch wheel capacitive sensor designs in white goods, mobile phones, media players, notebooks/netbooks, set top boxes, and other consumer and industrial electronic products.
