  • Package type
    

  - LQFP48
  

  - QFN32
  

  - QFN16
  

  • 4 I2C ID(2 external output option pins)
    
  • Calibration function can be set enable/disable
    
  • Each sensor sensitivity is individually programmable by 3 bits
    
  • 2 sensors (SI[0]/SI[1]) can work at slow mode, response time is 100~150ms(max. @3.0V)
    
  • One PWM could output via OUT[11:0]
    
  • Add external reset pin, active low
    
  • Auto-reset (calibration) function (default disable). If any key is touched more than 190 sec, chip will reset calibration function automatically.
