Automotive Grade Machine Permits for Simpler Integration Into House-Constrained Designs, Affords Excessive Decision of 0.0026 lx/ct for Placement Behind Darkish Cowl Glass
Vishay Intertechnology, Inc. launched the business’s first AEC-Q100 certified rectangular ambient gentle sensor. The Vishay Semiconductors VEML4031X00 options an ALS and extremely delicate IR photodiode in an opaque 4.38 mm by 1.45 mm surface-mount bundle with a low 0.6 mm profile. Occupying half the width of previous-generation options, the gadget permits for simpler integration into space-constrained designs, equivalent to bezel-less heart management shows.
Extremely correct measurements are supported because of the spectral sensitivity of the Automotive Grade sensor launched at the moment, which matches that of the human eye, whereas its IR channel permits for gentle supply differentiation. With an ambient gentle vary from 0 lx to 172 000 lx, the VEML4031X00 is not going to saturate in daylight, whereas its excessive sensitivity of 0.0026 lx/ct permits the gadget to be positioned behind darkish cowl glass.
Providing a excessive working temperature vary from -40 to +110 °C, the VEML4031X00 will likely be used for show backlight controls, infotainment techniques, rearview mirror dimming, inside lighting management techniques, and heads-up shows. The sensor helps the straightforward to make use of I²C bus communication interface for these purposes and provides an interrupt operate.
The VEML4031X00 contains a provide voltage vary of two.5 V to three.6 V, I²C bus voltage vary of 1.7 V to three.6 V and low shut down present consumption of 0.5 μA typical. RoHS-compliant, halogen-free, and Vishay Inexperienced, the gadget provides a Moisture Sensitivity Degree of 2a and a ground life of 4 weeks in accordance with J-STD-020.
