Vishay Intertechnology unveiled the industry’s first AEC-Q100-certified rectangular ambient light sensor. The Vishay Semiconductors VEML4031X00 features an ALS and a very sensitive IR photodiode in an opaque 4.38 mm by 1.45 mm surface-mount package with a low 0.6 mm profile.
The device is half the width of previous-generation solutions, making it easier to integrate into space-constrained designs like bezel-less center control displays.
The Automotive Grade sensor announced has spectral sensitivity comparable to the human eye, allowing for very accurate measurements, while its IR channel enables for light source discrimination.
The VEML4031X00, with an ambient light range of 0 lx to 172 000 lx, will not saturate in daylight, and its high sensitivity of 0.0026 lx/ct allows the device to be put behind dark cover glass.
The sensor supports the easy to use I²C bus communication interface for these applications and offers an interrupt function.
The VEML4031X00 Features:
- A supply voltage range of 2.5 V to 3.6 V,
- I²C bus voltage range of 1.7 V to 3.6 V and low shut down current consumption of 0.5 ?A typical.
- RoHS-compliant, halogen-free, and Vishay Green,
- The device offers a Moisture Sensitivity Level of 2a and a floor life of four weeks in accordance with J-STD-020.
Applications
Offering a high operating temperature range from -40 to +110 °C, the VEML4031X00 will be used for display backlight controls, infotainment systems, rearview mirror dimming, interior lighting control systems, and heads-up displays.
Availability
Samples and production quantities of the new ambient light sensor are available now, with lead times of 14 weeks.
