  • Patent number: 11099621
    Abstract: An information handling system real time clock (RTC)/CMOS circuit is powered from a battery that powers the information handling system. The battery power is supplied through a power management circuit that manages power constraints to the real time clock and that protects the battery from exceeding current and voltage thresholds. A protection integrated circuit selectively cuts off power supply from a power module to the RTC/CMOS circuit if predetermined conditions are detected. The protection circuit may also cutoff all power from battery with a permanent failure option or may itself directly supply power to the real time clock/CMOS circuit.
