Capacitive Touchscreen Controllers

Semtech capacitive touch controller ICs come in 8- and 12-channel models and feature integrated LED drivers. Our SX864x capacitive touch controller platform supports 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. Our SX863x capacitive touch controller platform provides the same wide range of button, slider and touch wheel features as the SX864x, along with the world’s longest range of proximity detection of 10cm. And unlike competitive alternatives, Semtech capacitive touch controllers integrate all the functional blocks necessary for capacitive sensing in a tiny footprint (without external components).
