Now that cars contain more lines of code than airplanes, it’s clear how vital electronic components are to vehicles. And it also goes without saying that there’s no room for compromise when it comes to automotive safety.

ISO 26262 is the automotive functional safety standard, addressing potential hazards that occur when electrical and electric systems in passenger vehicles malfunction. An adaptation of IEC 61508, ISO 26262, according to the International Standards Organization (ISO), provides:

  • An automotive safety lifecycle, from management to development, production, operation, service, and decommissioning
  • Automotive Safety Integrity Levels (ASILs, which utilize an automotive-specific, risk-based approach)
  • ASILs to specify applicable requirements of ISO 26262 to avoid unreasonable residual risk
  • Requirements for validation and confirmation measures that promote achievement of a sufficient level of safety
  • Requirements for supplier relations

Key Maxim battery management products have recently achieved third-party functional safety certification according to ISO 26262. This marks the highest achievable ASIL (ASIL D) on these products. Maxim’s functional safety product development process has also earned certification by TÜV Nord, a respected third party.

What does this mean for you? Using these battery management products will help you achieve the highest level of safety for your system as you complete your system safety assessment. Ultimately, these products will also help you get to market faster. These devices can serve as key components in EV battery packs, delivering the assurance of safe, reliable operation.
