Intersil Announces Industry’s First Automotive Low Light Ambient Light Sensor for AEC-Q100 Grade 2 Applications

The ISL76671 is the industry’s first low light ambient light sensor (ALS) that operates within the automotive temperature range of -40 degrees C to 105 degrees C, guaranteeing reliable performance without external temperature compensation. The sensor features internal temperature compensation, fast 30 millisecond response time and excellent infrared (IR) rejection. The ALS operates from a 1.8V to 3.0V supply with an ultra-low operating current of less than 4uA, and its voltage output can be connected directly to an ADC without buffering.

Available in a small 2.1mm x 2.1mm package, the ISL76671 is an ideal solution for light detection behind darkened glass and plastic bezels in a wide range of light-based control applications. The ultra-low light sensitivity (0.01 lux) enables excellent nighttime performance. (As a reference, the illumination from the full moon is typically from 0.25 to 1 lux, depending on location.)

Features and Specifications
• Light sensitivity down to 0.01 lux (range set by an external resistor)
• Near human eye spectral response with excellent IR rejection
• Voltage output can connect directly to ADC
• AEC-Q100 qualified for operation over the -40C to 105C temperature range
• 30ms response time responds to rapidly changing light conditions such headlamps, tunnels and shadows
• Small 2.1mm x 2.1mm package permits optimal placement of sensor

Pricing and Availability
The ISL76671 is assembled in a tiny 2.1mm x 2.1mm OFDN package with prices starting at $0.85 in 1,000-piece units. For more information please visit http://www.intersil.com/auto/new_products.asp#ISL76671
