SX9331
The PerSe Connect SX9331 features a unique smart engine, capable of accurately distinguishing between inanimate objects and the human body, which enhances Specific Absorption Rate (SAR) applications. 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 electromagnetic radiation sources to meet stringent emission regulations criteria and SAR standards. Operating directly from an input supply voltage of 2.7-3.6V, the SX9331 outputs its data via I2C serial bus. The I2C serial communication bus port is compatible with 1.8V host control to report body detection/proximity and to facilitate parameter settings adjustment. Upon proximity detection, the NIRQ output asserts, enabling the user to either determine the relative proximity distance or simply obtain an indication of detection. The SX9331 includes an on-chip auto-calibration controller that regularly performs sensitivity adjustments to maintain peak performance over a wide variation of temperature, humidity and noise environments, providing simplified product development and enhanced performance.
