Device Offers Excellent Temperature
Compensation in Compact 2.35 mm by 1.8 mm by 1.0 mm Package
The Optoelectronics group of Vishay Intertechnology, Inc.
(NYSE:VSH) today introduced a new integrated ultraviolet (UV) light
sensor featuring Filtron™ UV technology for high UV sensitivity and
linearity. Designed to convert solar UV light intensity to digital
data in consumer, medical, and industrial applications, the Vishay
Semiconductors VEML6070 incorporates a photo-pin-diode and signal
processing IC in a compact 2.35 mm by 1.8 mm by 1.0 mm
surface-mount package while offering an I²C bus interface for
simple operation.
The device released today is optimized for UV detection in
smartphones, health monitoring and fitness products, flame
detectors, and weather stations. The sensor saves space by
incorporating the circuitry needed for these applications in one
compact unit. A robust refresh rate setting lowers costs and
simplifies designs by eliminating the need for an external RC low
pass filter. The VEML6070 offers high dynamic detection resolution
and excellent 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 VEML6070’s built-in photo-pin-diode offers spectral
sensitivity from 280 nm 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 excellent temperature compensation stability from
-40 °C to +85 °C. The device features an operating voltage and I²C
bus voltage range of 2.7 V to 5.5 V and is offered in a lead
(Pb)-free OPLGA package. The VEML6070 is RoHS-compliant,
halogen-free, and Vishay GREEN.
Samples and production quantities of the new UV light sensor are
available now, with lead times of six to eight weeks for large
orders.
