DESCRIPTION

VEML6035 is a 16-bit low power, high sensitivity CMOS

ambient light sensor operated via a simple I2C command.

The sensor offers an active interruption feature that is

triggered outside of the threshold window settings

eliminating loading on the host. Active average power

consumption is around 300 μW.

VEML6035 incorporates a photodiode, amplifiers, and

analog / digital circuits in a single chip. Vishay’s patented

FiltronTM technology, a wafer level optical filter, provides

the best spectral sensitivity to match human eye responses.

The sensor has excellent temperature compensation to

maintain output stability under changing temperature and its

refresh rate setting does not need an external RC low pass

filter. There is a programmable shutdown mode which

reduces current consumption to 0.5 μA. Operating voltage

ranges from 1.7 V to 3.6 V.

APPLICATIONS

? Ambient light sensor for mobile devices (e.g. smart

phones, touch phones, PDA, GPS) for backlight dimming

even under tinted glass

? Ambient light sensor for industrial on- / off-lighting

operation

? Optical switch for consumer, computing, and industrial

devices and displays

AMBIENT LIGHT FUNCTION

? High ALS sensitivity with minimum detectable intensity of

0.0004 lux/bit supports low transmittance lens design
