Product Overview

VCNL4200 integrates a high sensitivity long distance proximity sensor (PS), ambient light sensor (ALS), and 940nm IRED into one small package. It incorporates photodiodes, amplifiers, and analog to digital converting circuits into a single chip using a CMOS process. The 16-bit high resolution ALS offers excellent sensing capabilities with sufficient selections to fulfill most applications whether a dark or high transparency lens design. For the 12-bit / 16bit proximity sensing function, VCNL4200 has a built-in intelligent cancellation scheme that eliminates background light issues. The persistence feature prevents false judgment of proximity sensing due to ambient light noise.
  • Integrated modules: infrared emitter (IRED), ambient light sensor (ALS), proximity sensor (PS), and signal conditioning IC
  • Operates ALS and PS in parallel structure
  • Filtron technology adoption for robust background light cancellation
  • Supports low transmittance (dark) lens design
  • Low power consumption I2C (SMBus compatible) interface
  • Output type: I2C bus (ALS / PS)
  • Proximity Function:
  • Immunity to red glow (940 nm IRED)
  • Intelligent background light cancellation
  • Smart persistence scheme to reduce PS response time
  • Proximity distance up to 1.5 m
  • Ambient Light Function:
  • Fluorescent light flicker immunity
  • Spectrum close to real human eye responses
  • Selectable maximum detection range (197/393/786/1573) lux with highest sensitivity 0.003lux/step
