Abstract:
A battery monitoring circuit is described. The battery monitoring circuit includes a high counter that increments when a sense voltage measurement is above a threshold. The battery monitoring circuit also includes a low counter that increments when the sense voltage measurement is below the threshold. The battery monitoring circuit further includes state machine circuitry coupled to the high counter and to the low counter. The battery monitoring circuit additionally includes open circuit voltage monitoring circuitry coupled to the state machine circuitry. The battery monitoring circuit also includes resistance monitoring circuitry coupled to the state machine circuitry.
