Designing safe LiDAR systems means meeting stringent safety requirements, including those
identified in ISO 26262, Failure Modes Effects and Diagnostic Analysis, and Automotive
Electronics Council-Q100. Maxim power protection ICs, supervisory circuits, and temperature
sensors provide valuable design options for addressing the safety requirements of LiDAR
systems.
"One significant trade-
off in LiDAR design is the
emitted power and the
eye-safety requirement.
One solution is to use a
narrow pulse-width laser,
but this requires more
powerful receiver-end
hardware. Fast receiver-
end hardware with low
system noise could be
beneficial."

"In a car, if a failure happens, the system needs to know it
happened so that it can be corrected and prevented in the future.
No failure should go unnoticed. A Failure Modes Effects and
Diagnostic Analysis predicts potential failures so that they can be
addressed before they happen."

Maxim power protection ICs:
• Monitor the input voltage to a load to ensure that it is within specified bounds to mitigate
the harmful effects of voltage spikes, reverse voltage, voltage shorts, fault conditions,
and similar conditions;
