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
