Ambient light sensor qualifies for automotive use
Intersil
ISL6683
Intersil has introduced the ISL6683, claimed to be the industry's first automotive-grade ambient light sensor, is suitable for measuring light levels in a wide variety of automotive applications.
Possible automotive applications include flat-panel display backlighting, courtesy lighting control and temperature-sensitive windshields.
Designed to support continuous operation up to 105C, the ISL76683 is qualified to the Automotive Electronics Council's AEC-Q100 grade 2, assuring reliability under significant thermal stress.
The integrated 16-bit analogue-to-digital converter core provides on-chip sensor signal conditioning along with user-programmable sensitivity to tailor performance for specific lighting conditions.
According to Intersil, the ISL76683 features built-in rejection of infrared and ultraviolet light, providing a close-to-human-eye sensitivity (lambda response), as well as 50 and 60Hz flicker elimination technology.
The sensor is temperature-compensated, removing the requirement to compensate for the vehicle's thermal environment.
In addition, light-level thresholds are programmable via I2C, enabling designers to set up an automatic monitoring system while simultaneously reducing system level control overhead.
The ISL76683 is available now, in compact six-pin OFDN packaging.
Pricing starts at USD1.25 (GBP0.77) each in 1,000-piece quantities.
