The ISL58344 photo sensor IC has a wide optical spectral
sensitivity from 400nm to 1000nm. It is good for multiple light
source applications, such as laser base projectors. The three
sets of gain registers can be used to adjust optical-to-electrical
conversion gain for each RED (R), GREEN (G), and BLUE (B)
laser or any wavelength in the spectral range for the
application. The ISL58344 is a single die device that has four
identical photo detectors arranged in segments that are
optimized for laser beam spot alignment. Quad segments can
be used as a single photo diode for optical power calibration
and gamma correction. The detectors can also be split into two
sections with subtraction signal output for laser beam position
alignment. Beam detection can also be used to compensate
for MEMS scanning projector geometric distortions and
temperature distortions. Registers can be updated in real time
while device is in operation.
The ISL58344 can be put in sleep mode through serial
interface, where it consumes virtually no power. The ENA pin,
when low, will put the device in standby mode. Toggling the
ENA pin Hi will turn the device on quickly.
The ISL58344 operates from a single +3.3V supply. It is
available in a space-saving 9 pin glass top BGA package.
