  • Abstract
    A rechargeable lithium battery safety IC designed for monitoring cell voltage and current in the battery is presented. The circuitry is capable of protecting batteries of one to four series connected cells via a programmable circuit architecture with a cell voltage limit accuracy of +/-1%. The circuitry has an average current drain of 25 μA. The Li safety IC with integrated series FETs has an area of 18.4 mm2
