Capacitive Touch Controllers and Proximity Sensing Solutions

Semtech Corporation

The SX9510 can operate autonomously using a set of programmable button sensitivities and thresholds, plus LED intensities and breathing functions with no external I²C communication required. All devices feature three individual LED driver engines for advanced LED lighting control. On the SX9510, proximity detection illuminates all LEDs to a pre-programmed intensity. The SX9300 is the world’s first dual channel capacitive Specific Absorption Rate (SAR) controller that accurately discriminates between an inanimate object and human body proximity. The resulting detection is used in portable electronic devices to reduce and control radio-frequency (RF) emission power in the presence of a human body, enabling significant performance advantages for manufacturers of electronic devices with electro-magnetic radiation sources to meet stringent emission regulations criteria and Specific Absorption Rate (SAR) standards.
