摘要：许多Maxim的电池监视器包含的选项包括一个内部检测电阻测量电流。本应用笔记讨论任何关注，自加热产生的电流通过检测电阻流可以引进片上温度测量误差。采取确定引进金额由内部检测电阻自加热的数据是一个独立的设备的情况下，加上热到电池设备的情况下提出的。此外，在无法容忍的自热效应的实例，校正计算，可以很容易地在软件中实现。 Application Note 197 Sense Resistor Power Dissipation www.maxim-ic.com Dallas Semiconductor’s battery management devices have the option to integrate the sense resistor into the package. While this feature reduces cost and board size, concern may arise that heat generated by the integrated sense resistor can cause the on-chip temperature sensing to be inaccurate. On the contrary, the following application note shows that the heat generated is not signi……
