ISL76683

Light-to-Digital Output Sensor with Gain Selection, Interrupt Function and I<sup>2</sup>C Interface

Product Status: Mass Production

OVERVIEW

The ISL76683 is an integrated light sensor with an internal integrating ADC intended for automotive applications. The ADC provides 16-bit resolution and is capable of rejecting 50Hz and 60Hz flicker caused by artificial light sources. The I2 C interface provides four user programmable lux sensitivity ranges for optimized counts/lux in a variety of lighting conditions. The I2 C interface also provides multi-function control of the sensor and remote monitoring capabilities.

In normal operation, power consumption is less than 300μA. Furthermore, a software power-down mode controlled with the I2 C interface reduces power consumption to less than 1μA.

The ISL76683 supports twin (upper and lower) user programmed thresholds and provides a hardware interrupt that remains asserted low until the host clears it with the I2 C control interface.

The ISL76683 is designed to operate on supplies from 2.5V to 3.3V, and is AEC-Q100 qualified and specified for operation across the -40°C to +105°C (grade 2) ambient temperature range. To achieve this, the ISL76683 is packaged in a special extended temperature clear package.
