Wide Optical Spectrum Laser Power Monitor IC

ISL58333

Features

The ISL58333 photo sensor IC has a wide optical spectral

sensitivity from 400nm to 1000nm. It is good for multiple light

source applications, such as laser based projectors. The

ISL58333 has two banks of three sets of gain registers. For a

Pico-Projector application, the two banks of gain resistors can be

used to monitor bias level and peak level of each wavelength.

Bank switching is done by applying a TTL compatible logic signal

to the HL pin. The three sets of gain registers can be used to

adjust optical-to-electrical conversion gain for each RED, GREEN,

and BLUE laser or any wavelength in a spectral range for

application. The ISL58333 is a single die device that has a photo

detector of 0.7mm diameter in the center of the die. The photo

current signal is amplified through the TIA, fine gain amplifier,

and the output drivers to convert from current to voltage. The

output of ISL58333 can be configured to be either differential or

single-ended. Gain changing according to each wavelength is

done through the I²C serial interface. Registers can be updated

in real time while the device is in operation.
