Abstract

In an example, a battery management system may include a host microcontroller, which may be operated in accordance with a first clock signal; and a first analog front end (AFE) circuit. The first AFE circuit may be operated in accordance with a second clock signal that may be unsynchronized with the first clock signal. The first AFE circuit may also include first digital circuitry to (1) accumulate a first value corresponding to a number of ADC sample cycles of the first ADC, and to (2) accumulate a second value corresponding to the digital output representative of the first battery current for the ADC sample cycles accumulated in the first value. The first AFE circuit may transfer a representation of the first value and a representation of the second value to the host microcontroller in response to a request from the host microcontroller.
