DATASHEET ISL76683 FN7697 Rev.10.0 May 21, 2021 Light-to-Digital Output Sensor with Gain Selection, Interrupt Function and I2C Interface Features 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 I2C interface provides four user programmable lux sensitivity ranges for optimized counts/lux in a variety of lighting conditions. The I2C interface also provides multi-function control of the sensor and remote monitoring capabilities. • Range select with I2C - Range 1 = 0 lux to 1000 lux - Range 2 = 0 lux to 4000 lux - Range 3 = 0 lux to 16000 lux - Range 4 = 0 lux to 64000 lux • Human eye response (540nm peak sensitivity) In normal operation, power consumption is less than 300µA. Furthermore, a software power-down mode controlled with the I2C interface reduces power consumption to less than 1µA. • Temperature compensated • 16-bit resolution 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 I2C control interface. • Adjustable sensitivity: up to 65 counts per lux 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. • IR + UV rejection • User-programmable upper and lower threshold interrupt • Simple output code, directly proportional to lux • 50Hz/60Hz rejection • 2.5V to 3.3V supply • 6 Ld ODFN (2.1mmx2mm) • AEC-Q100 qualified • Pb-free (RoHS compliant) Applications • Automotive ambient light sensing • Backlight control • Lighting controls VDD 1 MUX SHDN INT TIME GAIN/RANGE MODE PHOTODIODE 1 COMMAND REGISTER INTEGRATING ADC PHOTODIODE 2 DATA REGISTER I2C EXT TIMING IREF FOSC 5 SCL 6 SDA INT 216 COUNTER 3 2 REXT GND ISL76683 INTERRUPT 4 INT FIGURE 1.
