Abstract: Disclosed are a system and a battery management integration circuit using an incremental analog-to-digital converter (ADC), which can reduce the consumption of the amount of a bias current. The system includes an incremental ADC configured to perform accumulation on an analog signal during an oversampling period and a bias current generator configured to provide a bias current for the accumulation of the incremental ADC. The bias current generator provides a first amount of the bias current in a first period defined from start timing of oversampling to preset timing during the oversampling period, and provides a second amount of the bias current, smaller than the first amount of the bias current, in a second period subsequent to the first period.
