Active average power Optical switch for consumer, computing, and industrial consumption is around 300 W. devices and displays VEML6035 incorporates a photodiode, amplifiers, and analog / digital circuits in a single chip. Vishays patented AMBIENT LIGHT FUNCTION TM Filtron technology, a wafer level optical filter, provides High ALS sensitivity with minimum detectable intensity of the best spectral sensitivity to match human eye responses. 0.0004 lux/bit supports low transmittance lens design The sensor has excellent temperature compensation to maintain output stability under changing temperature and it s 100 Hz and 120 Hz flicker noise rejection refresh rate setting does not need an external RC low pass Excellent temperature compensation filter. There is a programmable shutdown mode which High dynamic detection resolution reduces current consumption to 0.5 A. Operating voltage ranges from 1.7 V to 3.6 V. INTERRUPT FEATURE (INT) SUPPORT Programmable interrupt function with upper and lowe r thresholds. Adjustable persistence to prevent false triggers.
