Automotive LiDAR ICs

Automotive-grade LiDAR products safely solve ADAS distance measurement challenges. Transimpedance amplifiers and ultra-fast comparators combine with protection ICs, supervisors, and voltage references in the design of innovative LiDAR modules while offering high reliability in small form factor products.

With safety as the main driver in ADAS applications, a wide range of supervisory products and protection ICs make the full LiDAR module more robust and reliable. Our automotive-qualified LiDAR solutions include microprocessors and high-accuracy supervisor window voltage monitors with watchdog timers. These supervisors set thresholds and reset timeout delays without external resistors or capacitors saving additional board area in space-constrained environments.
