ABSTRACT:
An integrated circuit for monitoring the voltage of a rechargeable battery and controlling, in accordance with such monitored voltage, the charging and discharging of such rechargeable battery. While disconnecting or, alternatively, powering down all other power consuming circuitry, the unloaded battery voltage is sampled. The sampled voltage is then stored in isolation while the remaining circuitry is connected or powered up for normal operation. The stored voltage sample, free from errors induced by the otherwise normal operation of the battery monitoring circuit, is then compared to a reference voltage.
