About – Elmos Laser Driver

Elmos Laser Driver is a scalable multi-channel laser-driver generating short high intensity pulses for direct time-of-flight measurements. Using a die stacking approach to minimize module size and  parasitic inductance, peak currents of up to 50A are applied to the laser-diodes within a 1ns pulse.

Advantages / USPs

  • Chip-stack-on-board design
  • Optimized for short pulses at high currents
  • Integrated diagnostics
  • Functional safety ready product
  • Automotive qualified
  • Cost-effective standard CMOS process
