  • Publication number: 20240072552
    Abstract: A power-saving charging device controls both a primary side controller and a secondary side controller to be in a shutdown state when an output terminal is not connected to the load. When the output terminal is connected to the load, the secondary side controller receives a power-on power supply from a power storage unit, performs a power-on procedure and enters a working state. The primary side controller receives a power-on signal from the power storage unit, performs the power-on procedure according to the power-on signal, and enters the working state. Accordingly, when the charging device is not connected to the load, it can enter a standby state with extremely low power consumption in which the primary side controller and the secondary side controller are both turned off, thereby achieving the effect of saving the power consumption of the controller when the charging device is in standby.

  • 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.
