最新模拟和电源产品帮助您满足功能安全要求
电子系统使汽车，工厂和家庭自动化更自主的操作。这是越来越多的电子和电气系统运行在接近彼此。例如，汽车有高压喷油器或大功率逆变器的混合驱动器，必须不受干扰的无线接收器。工厂可以有与工作秩序系统和物料输送机器人并存的大型计算机控制机器。这些系统中的每一个都需要自己操作安全，但也能够处理意外的干扰或故障在环境中，以避免伤害或丧失生命。
t is a high complexity problem. Functional safety standards such as IEC 61508 for industrial and ISO 26262 for automotive provide a framework for analyzing hazards， developing the safety concept to deal with those hazards， designing the proper hardware and software， and validating system safety performance.
However， compliance places additional burdens all along the development chain， from performing and documenting safety analyses， to managing tradeoffs between redundancy and risk mitigation. Semiconductor companies are now offering devices designed specifically to help designers meet their systems safety goals. Most recently， analog and power devices have joined microcontrollers in offering functional safety features.
