Capacitive touch controller

20 February 2013 Analogue, Mixed Signal, LSI

Semtech has developed the SX95xx platform of capacitive touch ICs for a wide range of home appliances and consumer electronics. The devices enhance the ECO mode present in many green home electronics by integrating an IR decoder for system wakeup. This enables the host to go into sleep mode during system standby and minimises the overall power consumption. The analog sensor front end in this platform is equipped with a high-resolution ADC which can detect down to 4 fF capacitance and is optimised for robust touch and proximity detection. These controllers also feature an advanced 256-step LED driver for various blinking and breathing controls, providing enhanced visual feedback.
