STMicroelectronics VM6101
The VM6101 is a high dynamic range 4-channel CMOS photosensor suitable for ambient light sensing as well as color light sensing. The signal period is readable through the two-wire serial interface. A power down input puts the VM6101 in ultra low power mode.FEATURES

DESCRIPTION
Light intensity is converted linearly to a variable frequency signal. A direct PWM output is provided for power saving LCD backlighting applications, where backlighting intensity adapts to the ambient light level. Alternatively, this output can be used as an ambient light level detector output, with two user programmable thresholds.
