In the automotive industry, electronic devices need meet more stringent requirements of AEC-Q10X vehicle standard. The working voltage platform of new energy vehicles is far higher than the safety voltage of the human body, so reliable isolation must be carried out between the high-voltage parts(such as the three electrical systems) and the low-voltage system, and the vehicle body. Hualian Semiconductor has achieved a comprehensive layout of automotive grade optocouplers, its products have passed AEC-Q101 automotive certification with quality in line with overseas top brands, and can provide reliable signal feedback isolation for the safe operation of the electronic control system.
