The primary purpose of the GW8318 is to detect the presence of users at varying distances, enabling the optimization of radio frequency (RF) emission power in the presence of the human body. The GW8318 empowers manufacturers of portable electronic devices with electromagnetic radiation sources to comply with stringent emission regulations and SAR standards, resulting in notable performance advantages.
The GW8318 communicates its data through the I2C serial bus, which is compatible with 1.8V host control. This communication allows for reporting body detection/proximity and facilitates easy adjustment of parameters. When proximity is detected, the NIRQ output is activated, offering users the option to determine the relative proximity distance or receive a detection indication only.
Equipped with an on-chip auto-calibration controller, the GW8318 can maintain peak performance across a wide range of temperature, humidity, and noise conditions. This feature ensures regular sensitivity adjustments, leading to simplified product development and enhanced overall performance.
