Headband Headphone Application Scheme Based on SEMTECH SAR SENSOR Intelligent Access Sensor

At present, Semtech proposes the combination of Smart Proximity Sensor intelligent proximity sensors and headband blue bud headphones to do headphones automatically start music, and automatically stop music, which is automatically stopped and saving electric power. The SX9324 outputs data through the I2C serial bus. I2C serial port Communication Bus Port Compatible with 1.8V Host Control Report Physical Detection / Proximity and Promoting Parameter Settings. When approaching detection, NIRQ output asserts that users can use the headset to automatically start music, and automatically stop music, which is automatically stopped, and the mechanism of power saving. ► Scene application map ► Product entity ► Present photo ► Forum block diagram ► GUI ► Headphones ► Headphones PCB 1 ► PCB ► Line map ► Core technology advantages The SX9324 is a capacitive than absorption rate (SAR) controller. SX9324 can be entered using two sensors coupled to their intelligence SAR's engine accurately divides a lifeless object and human body. Get detection for portable electronic devices to reduce and control radio frequency (RF) transmit power In the case of human body, significant electronic manufacturers' performance advantages. The equipment with electromagnetic radiation sources is strictly emission regulatory standards and specific absorption rates (SAR) standards. Working directly from 1.7 to 2V input power supply, SX9324 outputs data through the I2C serial bus. I2C serial port Communication Bus Port Compatible with 1.8V Host Control Report Physical Detection / Proximity and Promoting Parameter Settings. When approaching the detection, the NIRQ output asserts that the user can determine the relative approach distance, or simply obtain instructions. ► Scenario specifications ~ 1.8V input power supply voltage Up to 3 capacitive sensor inputs Patented SAR Sliced ​​Intelligent Engine Capacitor resolution is as low as 0.004FF Capacitor offset compensation is up to 200PF Advanced temperature compensation Automatic calibration Ultra-low power consumption Activity mode: 22 UA Snap mode: 6 UA Sleep mode: 1.75 UA 400kHzi2C serial interface 2 subactions can be selected by the pin. Programmable interrupt or real-time status pin Sourceful from big.
