Proximity Sensor

The GW8316 is an advanced 6-channel capacitive sensor MCU designed specifically for SAR (Specific Absorption Rate) applications. Capable of high-performance proximity detection based on capacitive sensing circuit operating with a wide range 2.7 V ~ 3.6 V supply voltage, this intelligent and smart sensor excels the presence detection of a user at various distances. With the human body proximity detection ability of the GW8316, radio frequency (RF) emission power can be optimized in the presence of the human body. The GW8316 provides noticeable performance benefits to portable electronic devices manufacturers by helping them to comply with stringent electromagnetic radiation regulations and SAR standards.

The GW8316 communicates to a host over the Inter-Integrated Circuit(I2C) serial bus, which can solely operate even in sleep mode. The Host can wake up the device from sleep mode with an I2C command. The interrupt signal output can be activated to allow the host to get the relative proximity distance or to receive a detection notification in an efficient way.

Equipped with an on-chip calibration functionality, the GW8316 can maintain performance across a wide range of temperatures, humidity, and noisy conditions. This feature allows for regular sensitivity adjustments, simplifying product development and improving overall performance.
