Module packages VCSEL sensor with MOSFET driver

This post was originally published on this site

ROHM has integrated VCSEL technology with MOSFET drivers in a module to achieve the shorter pulses and high output required for more accurate sensing. Conventionally, in VCSEL-equipped laser light sources, both the VCSEL device and MOSFET for driving the light source are individually mounted on the board. Consequently, the wiring length (parasitic inductance) between products …
