Vishay Intertechnology introduced a new ultraviolet (UV) light sensor for accurate detection of UVA and UVB light spectrum. The sensor can enable applications such as smartphones, smart watches, sport bands, notebook computers and weather stations by measuring UV sun exposure or UV index. This measurement is critical for people with an elevated risk of sunburn or anyone who is concerned about their sun exposure.
The VEML6075 contains photodiode, amplifiers, and analog / digital circuits into a single chip to save space in consumer, medical, and industrial applications.
For high UV sensitivity and linearity, the chip features Filtron technology. Individual UVA and UVB channels measure with 16-bit resolution and excellent sensitivity of 365 nm and 330 nm, respectively, said Vishay.
The VEML6075 offers excellent performance under long-term solar UV exposure and offers high temperature compensation stability from -40 °C to +85 °C for keeping the output stable under changing temperature.
A shutdown mode reduces power consumption to 800 nA, and an operating voltage range of 1.7 V to 3.6 V is ideal for portable electronics and wearable devices.
The device is offered in a compact 2.0 mm by 1.25 mm by 1.0 mm surface-mount package. It also offers an I2C bus interface for simple operation. Further, the VEML6075 is RoHS-compliant, halogen-free, and Vishay Green.
Samples and production quantities of the new UVA and UVB light sensor are available now, with lead times of 12 weeks for large orders.
