Description

GW8310

The GW8310 is an advanced 8-channel capacitive sensor designed specifically for SAR (Specific Absorption Rate) applications. Operating at a high-performance level with a voltage input of 1.8V, this intelligent and smart sensor excels in sensing user presence at multiple distances, thereby significantly enhancing SAR functionalities.

The GW8310 is designed to detect user presence at varying distances, optimizing RF emission power near the human body. This empowers portable device manufacturers to meet strict emission regulations and SAR standards, delivering notable performance advantages.

Using the I2C serial bus (compatible with 1.8V host control), the GW8310 reports body detection/proximity and facilitates parameter adjustments. When proximity is detected, the NIRQ output activates, providing users with distance information or a detection indication.
With an on-chip auto-calibration controller, the GW8310 maintains peak performance in diverse conditions, simplifying product development and enhancing overall performance.

On chip 8-bit microcontroller enables a capacitive sensor based SAR system that can provide standalone operation without the need for an external microcontroller or host system with the benefits of real-time processing of proximity data and customization and configurability for multiple applications.

GW8313

The primary purpose of the GW8313 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 GW8313 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 GW8313 communicates its data through the I2C serial bus, which is compatible with both 1.2V and 1.8V operation. 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 GW8313 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.
