IRS9100C

Overview

IRS9100C - high power, fast modulation frequency Laser (VCSEL) and LED illumination driver

The IRS9100C is a high power, fast modulation frequency Laser (VCSEL) and LED illumination driver. Fast rise and fall times allow it to be used for depth measurements e.g.: iToF and LDS systems.

High peak current allows for strong but short optical output bursts.

The IRS9100C comes in a small TSNP-10-4 package, while the integration of features like LVDS-, voltage- and thermal monitoring further reduce the applications footprint.
