IEC 62969-1:2017 pdf download.Semiconductor devices – Semiconductor interface for automotive vehicles
1 Scope
This part of IEC 62969 provides general requirements for performance evaluations and environmental conditions for the power interface of automotive vehicle sensors. For performance evaluations, various electrical performances such as voltage drop from power source to automotive sensors, AC noises and voltage level are included. For environmental conditions, various test conditions such as temperature, humidity and vibration are included. In addition, terms, definitions, symbols and configurations are covered in this part. NOTE Additional information on power interface for automotive vehicle sensors is provided in Annex A.
