TIDA-00992 汽车反向极性保护参考设计
反极性是汽车环境中所需的标准保护。当分离和重新连接电池电缆时，存在将电线连接到错误的电池端子的可能性。此错误可能会损坏电子控制单元 (ECU) 中的组件。为避免对 ECU 造成损坏，需要进行反极性保护。可以使用肖特基二极管，但将会产生持续高功率损耗。 该参考设计使用 LM5050-Q1，同时搭配 n 通道 MOSFET，可提供反极性保护并降低功率耗散。

Noise Measurement Post-Amp for Oscilloscope or Spectrum Analyzer
In some cases a scope or spectrum analyzer does not have the range required to measure very small noise levels. This noise measurement post-amp boosts the output noise of the device under test (DUT) to allow for measurement with standard test equipment. The key requirements of this circuit is that it has a low noise floor and sufficient bandwidth for characterization of most devices.
