Auxiliary power management devices are disclosed. In some implementations, an auxiliary power management device may be coupled to an auxiliary power source that serves as a backup power supply for a primary power source to provide power to an electronic device and comprising a plurality of switches to control currents of a plurality of energy storage components, a plurality of channels coupled to the plurality of switches, respectively, a plurality of switch controllers to control the plurality of switches coupled to the plurality of channels and monitor a current or voltage of the plurality of channels, and a management logic to control the switches coupled to the plurality of channels upon detection, by the plurality of switch controllers, of a first current or voltage distribution across the channels that exceeds a predetermined threshold regarding the current or voltage distribution.

Auxiliary power management device and electronic system including the same

The present technology includes a power supply and a method of operating the same. The power supply includes a main power supply configured to receive external power and output a charge voltage and main power, and an auxiliary power supply including a capacitor array configured to charge auxiliary power using the charge voltage and output the auxiliary power. The auxiliary power supply is configured to periodically repeat a discharge operation and a sub charge operation on the capacitor array when the charging of the capacitor array is started.
