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. 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. 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. 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.

Automotive Grade Ambient Light Sensors

The ISL76xx family features the first transparent package qualified for -40 to 105 degrees Celsius.


Another area that Intersil has ICs is ambient light sensors. In the past, we've had a large market share in portable devices like handsets, cell phones, cameras, etc. with our ambient light sensors. These devices are now migrating into the vehicle. So, there's a few key areas that they're used. They're used for adjusting the brightness on the lighting on your dashboards. They're also used within the mirrors in the vehicle where there is a sensor at the back of the mirror and a sensor now in the front of the mirror, where you actually, you detect the difference in light coming from headlights before you or from behind you. So, our ambient light sensors are designed specifically to meet automotive requirements. We are the only ambient light sensor supplier worldwide that meets the full requirements up to a 105 °C for our ambient light sensor packaging. All our competitors, the best they can get is up to 85 °C.

So, if you have an application where your ambient light sensor is on your dashboard or at the back of the mirror, overtime that will degrade with performance if it's only rated to 85 °C. So, our devices today are the only ones in the market rated to actually meet that requirement.
