The SL2001 and SL2002 are the first laser trigger system ICs to combine resonant capacitor charging and high-current laser diode triggering in a single device. This eliminates multiple external discrete components and inefficient conversion stages.
For example, using the SL2001 with a 400 W quad edge-emitting (EEL) laser module can reduce the laser system footprint by 80% (from 400 mm² to 80 mm²).
Both the SL2001 and SL2002 are packaged in a 14-pin package with a footprint of 3.5 mm². They offer resonant capacitor charging efficiency from Vin of up to 85% and can be used with EEL and VCSEL (vertical cavity surface-emitting lasers).
The SL2001 is designed for automotive-grade LiDAR applications and offers laser pulses with FWHMs below 2 ns, as well as a peak output power of 1000 W when operating on a 3 to 24 V power supply. The SL2002 is geared toward portable, battery-powered systems, operating on a 2.8 to 5.5 V source to deliver a 100 W pulse with a 1 MHz repetition rate.
“There is a huge need to integrate laser-based measurement into a wide range of applications, from automotive LiDAR to sports, hunting, industrial, logistics, and consumer systems,” said Ahsan Zaman, Director of Product Marketing at Silanna Semiconductor. “In all these applications, engineers need to reduce size, power losses, system complexity, and cost. We’ve had an incredible response to the preview presentations, so we’re thrilled to have moved into full production.”
1200V SiC Schottky Dodos for high-power infrastructure
Nexperia has announced the addition of two 1200V, 20A silicon carbide (SiC) Schottky diodes to its ever-expanding portfolio of power electronic components. The PSC20120J and PSC20120L models have been designed to meet the demand for lossy rectifiers...
