Package Technology Creates Robust Integrated Light Sensors

SensorEyeC devices from Melexis are integrated light sensors with a photodiode, transimpedance amplifier, output transistor and temperature compensation in a single chip.

The SensorEyeC series is designed for AEC-Q100 Grade 1 automotive applications, using patented package technology that enables high robustness, including 260°C solder reflow, with an undisturbed optical path.

The SensorEyeC series includes the MLX75303, MLX75304 and MLX75305. The MLX75303 is an easy-to-use Schmitt-trigger output light sensor that can be used for headlight control or contactless automotive switches. The MLX75304 converts light intensity into an output frequency, and features a highly linear response over a dynamical light input range of more than 100dB for applications such as rear-view mirror dimming and LED-light control. The MLX75305 converts light intensity into an output voltage, and features high linearity for ambient-light sensing.

All SensorEyeC components have a continuous operation lifetime qualified to over 15 years. These are available in SOIC8 open-cavity packages, as well as DFN packages, which measure only 3mm x 3mm x 0.65mm, with a temperature range from -40°C to 125°C.

 

FEATURES High linearity Low temperature dependency High precision Operating temperature range: -40°C to 125°C AEC-Q100 Grade 1

APPLICATIONS Cockpit and display dimming Rear-view mirror dimming Headlight control LED-light control Contactless switches
