Description
The HSDL-9001 is a low cost
analog-output ambient light
photo diode in lowest cost
miniature Quad-Flat-No Lead
(QFN) lead-free surface mount
package. It consists of a
photodiode, which peaks in
human luminosity curve at 550
nm. Hence, it provides an
excellent responsivity that is
close to the response of human
eyes, as shown in figure 2. It
provides a design-alternative to
the HSDL-9000 digital-output
ambient light photo sensor with
infinite ambient light detection
threshold control. Both the
HSDL-9000 and HSDL-9001 are
ideal for applications in which the
measurement of ambient light is
used to control display
backlighting. Mobile appliances
such as the mobile phones and
PDAs that draw heavy current
from the display backlighting will
benefit from incorporating the
HSDL-9000 and HSDL-9001 in
their designs to reduce the power
consumption significantly.
