Elmos has quietly expanded its automotive sensor portfolio with the E523.52
At its core, the E523.52 serves as a mixed-signal front end for time-of-flight lidar, controlling the optical emission and conditioning the return signal for external timing or DSP units. Elmos describes the part as a dedicated lidar IC that integrates up to four high-current laser channels alongside multiple transimpedance amplifiers for avalanche photodiodes, enabling both emitter and receiver paths on the same chip. This single-package approach allows Tier-1 suppliers to design more compact lidar heads and reduce the number of discrete components on multi-layer boards, which can lower material costs and simplify qualification in automotive projects. The manufacturer also highlights built-in protection and diagnostics functions such as overcurrent monitoring on the laser outputs and supply supervision for safer lidar operation in vehicles. The analog front end of the E523.52 is tailored to the short, high-energy pulses that characterize typical automotive lidar systems, with Elmos specifying adjustable pulse widths in the nanosecond range and peak currents that can drive standard 905 nm laser diodes used in roof-, grille- or headlamp-integrated sensor units. Fast transimpedance stages on the receive side convert the very small avalanche photodiode currents into usable voltages, supporting long-range detection when paired with suitable optics and time-of-flight processors. To help engineers with layout, the chip comes in an automotive-qualified package with defined thermal characteristics and pinout optimized for short current paths, which is crucial to keep ringing and EMI under control in high-speed lidar designs. Elmos positions the E523.52 within its broader portfolio of sensor and driver ICs for automotive applications, which also includes ultrasound, pressure, and motor-control solutions for comfort and safety systems. While lidar is still a niche compared with camera and radar in mass-market vehicles, the company is targeting premium driver assistance features and selected industrial platforms where precise 3D mapping and object classification are required. As more OEMs experiment with combining multiple sensing modalities, a compact and integrated lidar signal chain like the one enabled by the E523.52 can make it easier to package sensors unobtrusively in the vehicle body or behind the windshield, where space and thermal budgets are tight. For development programs, Elmos typically provides evaluation boards and reference designs for its lidar front-end ICs, allowing system suppliers to test the driver and receiver path with different laser diodes and avalanche photodiodes. The company also supports functional safety concepts and offers documentation to help customers align their lidar modules with automotive qualification standards such as AEC-Q100 and ISO 26262, depending on system architecture. Because the E523.52 sits close to the optical path and handles high-speed switching, careful PCB design, shielding, and grounding are still necessary, but integrating driver and receiver functions in one device can significantly shorten design cycles compared with fully discrete approaches. Within Elmos’ revenue mix, driver assistance and sensor-related ICs are one of several pillars alongside powertrain, body electronics, and comfort applications; lidar-specific parts are currently a smaller but strategically important segment that positions the group in emerging ADAS architectures. Shares of Elmos Semiconductor SE (ISIN DE0005677108) are listed on Xetra, where the stock last traded at EUR 94.40 on 06/14/2026.
