Vishay Semiconductors VEML6070 integrated UV light sensor

Designed to convert solar UV light intensity to digital data in consumer, medical and industrial applications, the Vishay Semiconductors VEML6070 comes in a compact 2.35 x 1.8 x 1 mm surface-mount package. The integrated UV light sensor features Filtron UV technology for high UV sensitivity and linearity.

The device is optimised for UV detection in smartphones, health monitoring and fitness products, flame detectors and weather stations. The sensor incorporates the circuitry needed for these applications in one compact unit.

A robust refresh rate setting simplifies designs by eliminating the need for an external RC low pass filter. The product offers high dynamic detection resolution and good performance under long-term solar UV exposure, while an active acknowledge (ACK) feature with threshold window settings sends out UVI alert messages under strong solar conditions.

The built-in photo-pin-diode offers spectral sensitivity from 280 to 400 nm, with a peak sensitivity wavelength of 355 nm. The sensor provides fluorescent light flicker immunity, a software shutdown mode to reduce power consumption to <1 µA and temperature compensation stability from -40 to +85°C.

The product features an operating voltage and I²C bus voltage range of 2.7 to 5.5 V. Offered in a lead-free OPLGA package, the device is RoHS-compliant, halogen-free and Vishay GREEN.
