AECQ Proximity Sensor with Four I²C Address Options for Multi-Sensor Applications


  • Integrated modules: IRED, ALS, PS and signal conditioning IC
  • Operates ALS and PS in parallel structure
  • FiltronTM technology adoption for robust background light cancellation
  • Ambient light photo diode offers detection from 0.004 lx to 4.2 klx

VCNL4030X01 integrates a PS, ALS and a high power IRED into one small package. It incorporates photodiodes, amplifiers, and analog to digital converting circuits into a single chip by CMOS process. The 16-bit high resolution ALS for excellent sensing capabilities with sufficient selections to fulfill applications whether dark or high transparency lens design. ALS and PS offer a programmable interrupt with individual high and low thresholds offers the power savings on the microcontroller and features an intelligent cancellation scheme - cross talk is eliminated effectively.
