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.
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.
A power down input puts the VM6101 in ultra low
power mode.
The VM6101 is housed in an compact 8-lead
surface mount clear plastic package, compliant to
RoHS directive.
