Silanna Semiconductor, an analog innovation, releases new FirePower series of laser driver ICs, introducing what it describes as the smallest and most efficient platform currently available for LiDAR and time-of-flight applications.
The first product in the series, the SL2001, is a 14-pin, 3.5 mm² integrated circuit that combines both high-voltage charging and laser firing functionalities on a single chip. This integration marks a significant departure from traditional LiDAR systems, which typically rely on multiple components to manage power regulation and laser operation.
According to Silanna, the new chip enables up to 73% improvement in VIN-to-laser efficiency and supports peak laser outputs of up to 1000 W. Additionally, the chip reduces the physical footprint of a 400 W quad Edge-Emitting Laser (EEL) module from 400 mm² to 80 mm², representing an 80% reduction in size.
The SL2001 operates within a 3 V to 24 V supply range and supports both EEL and Vertical Cavity Surface Emitting Lasers (VCSELs). It can generate laser pulses with a sub-2 nanosecond full-width at half-maximum (FWHM) and offers a pulse repetition frequency exceeding 10 MHz. Other notable features include sub-0.1 ns peak-to-peak jitter in the Laser Fire output and integrated laser output sensing and control to meet eye-safety standards.
The device also offers programmability via an I²C interface and incorporates multi-time programmable ROM, eliminating the need for an onboard microcontroller. It includes functionality to monitor and respond to both input voltage and resonant capacitor voltage, enhancing system adaptability.
The FirePower series is designed for use in LiDAR and other high-speed sensing systems across industrial, automotive, and emerging technology sectors. By integrating key functionalities, the platform aims to simplify design, reduce bill of materials (BOM) costs, and support the development of smaller, more efficient laser-based systems.
“LiDAR applications have traditionally required multiple external components to manage high-voltage charging and firing,” said Ken Boyden, Product Marketing Director at Silanna. “The SL2001 consolidates these functions, setting new performance and efficiency benchmarks for the industry.”
The SL2001 is available immediately in a compact 1 x 3.5 mm WLCSP package, with evaluation kits and samples offered for design and testing purposes.
