Highly integrated VCSEL driver ICs for small module size and low BOM

anchor

Overview

Infineon's VCSEL drivers have been developed with a focus on driving fast switching dual- or triple-junction VCSEL (Vertical Cavity Surface Emitting Laser) providing optimal power efficiency and seamless integration. The devices are optimized for 3D vision camera systems in combination with Infineon’s REAL3™ Time-of-Flight (ToF) imagers and are suitable to other active infrared applications like laser distance scanner (LDS) and other lidar systems.

Key Features

  • Fast-switching laser diodes or LEDs
  • Tailored to high-performance 3D cam
  • Fast rise and fall times < 0.8 ns
  • Low power consumption
  • Built-in fail-safe functions
  • Small IC footprint

Infineon's VCSEL driver ICs for next-generation 3D cameras

Infineon's VCSEL driver ICs are designed to streamline the development and production of high-performance 3D cameras. Compared to discrete illumination driver concepts, these highly integrated VCSEL drivers reduce the number of components and simplify circuit complexity.

The VCSEL drivers feature a voltage-mode driver architecture optimized for use with Infineon's REAL3™ Time-of-Flight image sensors. The integrated LVDS input interface enhances signal integrity and ensures EMC robustness. Additionally, the drivers can be efficiently powered by an existing 3.3V supply for the imager. Combined with the imager's integrated current monitor for eye-safe designs, the REAL3™ bundle forms the most compact and cost-effective ToF module solution.

These driver ICs are also suitable for other fast-switching, laser-powered applications using a voltage-mode driver architecture, supporting both VCSEL and LED illumination types.
