Maximising battery measurement AFEs

Posted: 09 Jun 2014  Print Version  Bookmark and Share

Keywords:MAX14920/MAX14921  battery-measurement  analogue front-ends  AFEs  flat discharge 

The MAX14920/MAX14921 are battery-measurement analogue front-ends (AFEs) for monitoring up to 12 and 16 battery cell voltages, respectively. The accuracy and sample-and-hold architecture of the MAX14920/MAX14921 is ideal for monitoring cell chemistries with nearly flat discharge curves, such as lithium phosphate cells, but it can also be used in applications where accuracy is not the tightest constraint.

As a building block, the overall performance of the MAX14920/MAX14921 is highly dependent on the network of ICs surrounding it. This application note provides a framework for, and examples of, selecting system building blocks that meet diverse accuracy and cost requirements.
