SX9306

Ultra Low Power,

Smart Proximity Sensor for SAR

WIRELESS & SENSING

GENERAL DESCRIPTION

KEY PRODUCT FEATURES

The SX9306 is an ultra-low power capacitive Specific

Absorption Rate (SAR) controller that accurately

discriminates between an inanimate object and human body



2.7 – 5.5V Input Supply Voltage

Up to 4 Capacitive Sensor Inputs



Patented On-Chip Smart Engine for Human Detection and

Advanced SAR Control

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,



High Resolution Capacitive Sensing down to 0.08fF

Capacitance Offset Compensation up to 30pF

Configurable Proximity Detection (single/combined)

Integrated High Performance RF Shield for Enhanced

Noise Immunity

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.

Operating directly from an input supply voltage of 2.7 to

5.5V, the SX9306 outputs its data via a 1.65 – 5.5V host

compatible I2C serial bus.



Extremely Low Temperature Drift for Stable Measurement

Reduced VDD Ripple Susceptibility



Active Sensor Guarding

Automatic Calibration

Ultra Low Power Consumption:

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.



400kHz I2C Serial Interface



Four programmable I2C Sub-Addresses

Input Levels Compatible with 1.8V Host Processors

The SX9306 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.



Open Drain NIRQ Interrupt pin

Up to Three Reset Sources: POR, Soft Reset, NRST

-40°C to +85°C Operation

In QFN package, a dedicated transmit enable (TXEN) pin is

available to synchronize capacitive measurements for

applications that require synchronous detection, enabling

very low supply current and high noise immunity by only

measuring proximity when requested.
