For in-vehicle lighting, Intersil claims that its ISL76683 is the industry's first automotive grade, ambient light sensor designed to support continuous operation up to 105°C. The sensor is qualified to AEC-Q100 grade 2, for significant thermal stress. It also maintains package transparency under automotive thermal stress. The package measures light levels in flat panel display backlighting, courtesy lighting control and temperature-sensitive windshield applications. The integrated 16bit ADC core provides on-chip sensor signal conditioning with user programmable sensitivity to tailor performance for specific lighting conditions. The sensor's light level thresholds are programmable via I²C, enabling designers to set up an automatic monitoring system while simultaneously reducing system level control overhead.
