Description
The VM6101 is a high dynamic range 4-channel CMOS photosensor suitable for ambient light sensing as well as color light sensing. Light intensity is converted linearly to a variable frequency signal. The signal period is readable through the two-wire serial interface.

Features
■ 4-channel Y+RGB photosensor, with integrated infrared filter
■ Wide dynamic range light to frequency converters
■ 2-wire serial interface, I²C and SMBus compatible
■ PWM output for direct LCD backlight control
■ Comparator logic with two programmable thresholds and hysteresis function
■ Power down input
■ 3.0 V to 3.6 V supply range
■ Built-in clock generator, precision voltage and current references
■ Low profile Pb-free package (RoHS compliant)

Applications
■ General purpose color measurement
■ Automatic backlighting control
■ Panel lighting
■ White goods
