Laser Driver IC

Infineon Vertical Cavity Surface Emitting Laser (VCSEL) drivers have been developed with a focus on providing optimal power efficiency, fast switching and seamless integration into various applications. The devices can be implemented in 3D vision camera systems in combination with Infineon’s REAL3™ Time of Flight (ToF) imagers, or in line laser scanner (LDS) and other lidar systems. Precise and high-power turn-on characteristics make it an ideal illumination driver for any application needing accurate 3D depth measurements.

The driver ICs integrate an LVDS receiver, gate driver and switch components within a tiny package and can be fully powered by the anyway existing 3.3V imager power supply. As such, the VCSEL drivers allow for reduced number of components and less circuit complexity compared to discrete illumination transmitter concepts.

The Infineon illumination driver devices are suited for solutions based on VCSEL or LED.

The REAL3™ product portfolio also comprises ToF imagers for consumer applications and automotive applications.

Key features and benefits:

1. Highest versatility: Infineon’s VCSEL driver portfolio support single-, dual-, and triple-junction VCSEL technologies, ensuring a seamless integration into a wide range of camera applications.
2. Fast switching behavior: with rapid switching behavior of up to 250 MHz, the VCSEL drivers enable precise and responsive operation. This capability allows for accurate data acquisition and enables high-speed optical communication in your applications.
3. Robust performance: The high integration level of the VCSEL drivers provide best performance and most robust operation, as less component tolerances have to be considered in the illumination design.
4. Ultra-Small packages: Infineon's VCSEL drivers are available in tiny packages, offering significant space savings and allowing for more efficient design integration.
5. Integrated fail-safe functionality: Infineon's VCSEL drivers provide integrated fail-safe functionality in the event that thermal protection, LVDS input and supply monitoring requires it. This eliminates the need for additional components, simplifying the system design and module dimensions.
6. Cost optimization: The highly integrated VCSEL drivers reduce the bill of materials (BOM) contributing to overall cost savings, in special when combing the drivers with Infineon’s REAL3™ Time-of-Flight imagers.
