摘要： An integrated circuit (IC) includes input/output (I/O) ports, each operating using one of a pair of unequal power supplies during normal operation of the IC. A lower supply of the pair of unequal power supplies is required to be used as the power supply for the I/O port when a first input signal to the IC is received from an external source on a first I/O port of the I/O ports. The voltage range of the logic excursions of the first input signal is greater than the range from a magnitude of the lower supply to a constant reference potential. A regulation loop derives a derived lower supply having a magnitude equaling that of the lower supply from the higher supply of the pair of unequal power supplies, and applies the derived lower supply on a power supply node of the first I/O port.

An example apparatus includes a primary power management integrated circuit (PMIC) to communicate with an embedded system to determine a power state. The example primary PMIC is to include a first power state sequence controller and a first power supply controller. The example first power state sequence controller is to drive a first power supply controller according to the power state. The example first power supply controller is to activate a first set of rails to apply power to the embedded system. The example apparatus includes a secondary PMIC including a second power state sequence controller and a second power supply controller.

摘要： A technique and components of a device to manage power distribution of multiple energy sources based on one or more feature(s) associated with the device. The device includes at least a first battery module associated with a first mode and a second battery module associated with a second mode. The device can receive from one or more sensor(s), sensor data indicating one or more feature(s) associated with the device. The device can determine the second mode based on the one or more feature(s), and switch to the second mode. Based on the second mode, the device can determine the second battery module to provide power to the device and cause the second battery module to distribute electric power to the device.

摘要： In a network data center, a plurality of modules provide power to equipment racks. Each of the modules has a plurality of taps which are connected by internal switching elements to power mains through an internal power distribution bus, such that each of the modules can switch any of the plurality of taps to two of the three phases of power. Each of the equipment racks has a multi-branch power distribution unit, branches of which may be connected together to receive power from the same tap. The number of branches in each multi-branch power distribution unit is configurable to adapt to the power requirements of the equipment rack. Power and control signals for the logic and control circuits of the modules are supplied separately from the power mains by a coordinating computer which has the modules connected in a redundant ring topology.

摘要： Systems and methods manage use of rechargeable battery power of Information Handling Systems (IHSs). In managing power draws from the batteries of an IHS, use of software applications of the IHS is monitored and use is detected of a software application that has been designated as prioritized for use of the IHS batteries. A power throttling factor is selected for use in drawing power from the rechargeable batteries of the IHS while the prioritized software application remains in use. The selected power throttling factor is transmitted to an embedded controller of the IHS and the embedded controller is notified when the prioritized software application is no longer in use by a user of the IHS. The embedded controller receives the power throttling factor and, while the prioritized software application remains in use, the embedded controller limits power drawn from the IHS rechargeable batteries according to the power throttling factor.
