Optoelectronics Semiconductors drive EPC FET LASER

EPC21701 laser driver monolithically integrates an 80V, 40A FET with gate driver and 3.3 logic level input into a single chip for time-of-flight lidar systems used in robotics, surveillance systems. Device is tailored to lidar systems for gesture recognition, time of flight (ToF) measurement, robotic vision, or industrial safety. Device uses 5V supply voltage and is controlled using 3.3V logic. Product is capable of very high frequencies greater than 50MHz and super short pulses down to 2ns to modulate laser driving currents up to 15A. Voltage switching time is less than 1ns and delay time from input to output is less than 3.6ns.
