The LMH13000 is the industry’s first integrated laser driver to deliver an ultra-fast 800ps rise time and 50mA to 5A adjustable output current with only 2% variation across temperature, enabling lidar modules in automobiles and autonomous mobile robots to measure objects more accurately and at up to 30% longer distances than today’s lidar systems.

A rise and fall time of 800ps for pulsed current-output capability, and active current control supporting up to 1A continuous or 5A pulsed current, depending on frequency, up to 250MHz. The device’s short pulse width generation and current control enable the system to meet Class 1 FDA eye safety standards. Using multiple LMH130000 devices in parallel can increase the amount of current going to the laser to as much as 5A. Since the LMH13000 does not require an external FET nor large capacitors, it is possible to decrease the size of the laser driver solution by four times compared to discrete solutions. Because of the integration, companies can save an average of 30% on system costs from previous lidar module system designs.
