Laser drivers for light distancing and ranging (lidar) are used in a pulsed-power mode. What are the basic requirements for these laser drivers?
A new family of integrated laser driver ICs meets all these requirements. The first release, the EPC21601 laser driver IC, integrates a 40 V, 10 A FET with integrated gate driver and 3.3 V logic level input in a single chip for time-of-flight (ToF) lidar systems used in robotics, surveillance systems, drones, autonomous cars, and vacuum cleaners. This chip offers frequency capability up to 200 MHz in a low inductance, economical, 1 mm x 1.5 mm BGA package.
