The SX95xx platform of capacitive touch ICs is suitable for a wide range of home appliances and consumer electronics. The feature-rich touch-button family enhances the eco mode present in many green home electronics by integrating an IR decoder for system wake up. This enables the host to go into sleep mode during system standby and minimizes 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 of capacitance and is optimized for robust touch and proximity detection. These controllers also feature an advanced 256-step LED driver for various blinking and breathing control providing enhanced visual feedback in TV applications.
Each device is designed with unique innovative circuitry that combines the capacitive sensor with the LED driver to reduce the overall solution footprint. The SX9510/11/12/13 are in an eight-channel configuration and are offered in space-saving 4 x 4-mm 20-QFN and 4.4 x 7.8mm 24-TSSOP packages; and the SX9500/01 provide four channels in a tiny 3 x 3-mm 20-QFN package.
Additional features include enhanced proximity sensing (SX9510/12), integrated IR decoder for eco system design (SX9510/11), built-in LED drivers for visual feedback (SX9510/11/12/13), and-chip buzzer control for audible feedback (SX9510/11/12/13).(Contact company for pricing — available now.)
