用于重复雪崩的汽车ASFET

有保证的重复雪崩性能,符合汽车标准

使用MOSFET为驱动电磁阀等感性负载供电时,大多数电路设计包含附加的器件,以便当负载电流在关断期间持续流动时保护MOSFET。解决方案包括高效但昂贵的升压拓扑(可重复利用能量),以及效率较低但更经济实惠的续流二极管方案。重复雪崩装置的简单替代方案在过去只能通过平面技术来实现。Nexperia通过优化MOSFET,使其能够轻松应对重复雪崩电流,同时将结温保持在175 ℃以下,从而提供了一种真正耐用的器件,实现了大量的系统级节约。

重复雪崩的ASFET

用于重复雪崩的ASFET专为满足一系列汽车和感性负载的需求而设计:

  • 符合AEC-Q101标准
  • 有保证的重复雪崩性能,经过高达10亿个周期的测试
  • 稳健的硅技术与LFPAK的热性能相结合,确保芯片温度保持在175 ℃以下
  • 使用单个MOSFET非常简便,减少了BOM和电路复杂性,实现了系统成本和空间节约
  • 用现代沟槽替代旧式平面技术
  • 与续流二极管方案相比,提供了更高的效率和更快的开关
