Hello, afe chip refers to the analog front-end chip, its main function is to collect, amplify and filter the analog signal, convert the analog signal in the actual environment into a digital signal, facilitate the digital signal processor to carry out subsequent digital signal processing, and the processed signal back to the analog signal, output to the external device. afe chips are widely used in medical, industrial automation, communications, automotive electronics and other fields. In the medical field, afe chips can be used for ECG monitoring, blood sugar detection, blood oxygen monitoring and other biological signal collection.
In the field of industrial automation, afe chips can be used for sensor signal acquisition, temperature and pressure monitoring.
AFE (analog front end), Chinese is analog front end, in BMS specifically refers to the battery sampling chip, used to collect cell voltage and temperature.
Before writing this, I thought for a long time, there are too many places to write AFE, and a small place can be pulled for a while; In the end, I decided to start with a question and introduce a little AFE-related stuff in the middle, so that the content would not seem too stiff and dogmatic.
afe chip is a chip used to build discrete devices in battery systems.
