Azoteq IQS263 ProxSense Capacitive Touch and Proximity Controller

Azoteq IQS263 ProxSense® Capacitive Touch and Proximity Controller is offered as the first proximity controller specifically designed to meet the latest SAR regulations (KDB 616217-D04 and IEC 62209-2 ed1.0). Featuring 3 input channels, the IQS263 can detect proximity to meet SAR regulations in multiple points and also be used to detect a stylus or smart cover. Designers can configure the IQS263 as a three channel slider or scroll wheel. The device can also be configured as a two channel slider with one key or utilize the third channel for long range proximity detection. The design also features a unique movement sensor to prevent stuck conditions, automatic tuning for sense electrodes, internal reference capacitor, and internal regulator to reduce total system cost. With the best-in class-sensitivity, signal-to-noise ratio, and power consumption, the IQS263 is ideal for SAR detection for tablets and mobile phones, SAR detection for wireless charging stations (operating frequency > 100MHz), SAR detection for USB dongle-type devices, sliders/scroll wheels for remote controls, movement detection devices (anti-theft), volume control & lid closure detection for laptops, MP3 players, portable electronics, and wearable electronics.
