A brand new rectangular ambient mild sensor combines excessive sensitivity, IR detection, and ultra-low energy in a compact package deal—very best for bezel-less automotive shows and harsh environments.
Vishay Intertechnology, Inc. has unveiled the trade’s first AEC-Q100 certified ambient mild sensor in an oblong type issue. The brand new VEML4031X00 combines an ambient mild sensor (ALS) and a high-sensitivity IR photodiode inside an ultra-compact 4.38 mm x 1.45 mm x 0.6 mm surface-mount package deal — almost half the width of earlier options. Its slim profile makes it very best for tight areas, similar to bezel-less automotive management shows.
The important thing specs embrace:
- Provide voltage vary: 2.5 V to three.6 V
- I²C voltage help: 1.7 V to three.6 V
- Extremely-low standby present: 0.5 μA
- Huge working temperature: -40 °C to +110 °C
- Dependable efficiency in harsh environments
The sensor gives excellent precision, with spectral sensitivity intently aligned with the human eye. An extra IR channel permits mild supply differentiation. With a detection vary spanning 0 lx to 172,000 lx, the VEML4031X00 maintains correct readings even in vibrant daylight. Its spectacular sensitivity of 0.0026 lx/ct permits it to perform successfully behind darkish or tinted cowl glass.
Functions embrace automotive infotainment techniques, backlight dimming, inside lighting, rearview mirror dimming, and heads-up shows. The system integrates simply into designs through an I²C communication interface and contains an interrupt perform for added flexibility. The sensor meets RoHS compliance, is halogen-free, and Vishay Inexperienced, with a Moisture Sensitivity Degree of 2a and a flooring life of 4 weeks per J-STD-020. It’s now out there in each pattern and manufacturing portions, with a lead time of 14 weeks.
