Abstract
A status of one or more components of a battery monitor circuit can be evaluated, such as to validate operation of the monitor circuit. In an example, a battery monitor circuit can be evaluated by providing a first test signal to a battery voltage measurement circuit that is coupled to a battery. A first analog-to-digital converter (ADC) circuit can be configured to receive a first voltage signal from the battery voltage measurement circuit in response to the first test signal. A processor circuit can be configured to validate the first ADC circuit by evaluating a correspondence between the first test signal and the received first voltage signal. One or more other ADC circuits in the battery monitor circuit can be validated by cross-checking measurement results with information from the first ADC circuit.
