VEML6075
Vishay Semiconductors
UVA and UVB Light Sensor with I2C Interface
DESCRIPTION
The VEML6075 senses UVA and UVB light and incorporates
photodiode, amplifiers, and analog / digital circuits into a
single chip using a CMOS process. When the UV sensor is
applied, it is able to detect UVA and UVB intensity to provide
a measure of the signal strength as well as allowing for UVI
measurement.
The VEML6075 provides excellent temperature compensation
capability for keeping the output stable under changing
temperature. VEML6075’s functionality is easily operated via
the simple command format of I2C (SMBus compatible)
interface protocol. VEML6075’s operating voltage ranges
from 1.7 V to 3.6 V. VEML6075 is packaged in a lead (Pb)-free
4 pin OPLGA package which offers the best market-proven
reliability.

APPLICATION INFORMATION
Pin Connection with the Host
The configuration and data registers of the VEML6075 are accessed via the I2C interface. The hardware schematic is shown
below in fig. 6.
The 0.1 μF capacitor near the VDD pin is used for power supply noise rejection. The 2.2 kΩ is suitable for the pull high resistor
of I2C.
