Abstract: An information handling system data port system includes plural data ports that support communication of data and power transfer with external devices, such as peripherals. A power transfer manager selectively establishes direct power transfer between data ports in support of power transfer between external devices, such as one external device acting as a power source and another external device acting as a power sink. The power transfer manager establishes direct power transfer with switches that bypass the information handling system power subsystem to provide improved power transfer efficiency.

Abstract: A system and method for enhancing ground bounce immunity of cables such as USB type-C cables. More specifically, in certain embodiments, ground bounce immunity is enhanced by making use of alternate modes of operation of cables conforming to the USB 3.1 specification to achieve a higher power over a cable that conforms to the USB 3.1 voltage drop specification requirements on the ground signal paths when the cable is operating at normal power levels (i.e., at a power level supported by the USB 3.1 specification). In certain embodiments, ground bounce immunity is enhanced by making use of alternate modes of operation of USB 3.1 type cables and standard use USB3.1 power delivery negotiation protocol to allow a host and end device to negotiate higher power than what would normally conform to the USB 3.1 specification.

A cable couples first battery module port to a portable information handling system port to provide power to the portable information handling system and accept power from the portable information handling system. Plural additional battery modules daisy chain to the first battery module to accept power from and provide power to the portable information handling system. Power transfer is coordinated with communications through the ports, such as by a USB power transfer protocol supported at the information handling system and each battery module.

Abstract: An information handling system receives power from a reversible power cable by selectively configuring outer pins to provide power or communication with a middle pin providing ground. A power manager of an information handling system embedded controller uses a low level of power input to determine which outer pin provides power and which provides communication, and then configures the connector to route power at a high level to the system charger for powering the information handling system.

A controller module includes logic to coordinate power transfer to and from an information handling system. An AC-to-DC adapter module couples to the controller module to provide power from an AC power source to the information handling system through the controller module, which coordinates power transfer with the information handling system. A battery power source module couples to the controller module to provide battery power, with the battery charged by power from either the information handling system or the AC-to-DC adapter module.

The user interface provides users with real time information for power and data transfer configurations that help optimize information handling system performance.

Abstract: An information handling system can receive power from a wireless or wired power source. In response to determining the information handling system is coupled to the wired power source, the system decouples the wireless power source from providing power. In response to the system being decoupled from the wired power source, the information handling system couples the wireless power source to the system.

Abstract: Power is supplied to an information handling system chipset with a single voltage regulator having dual phases. A first phase of the voltage regulator provides power to a low power state power rail in an independent mode to support a low power state, such as a suspend or hibernate state. A second phase of the voltage regulator provides power to a run power state power rail in combination with the first phase by activation of a switch, such as a MOSFET load switch, that connects the low power state power rail and the run power state power rail. Voltage sensed from both power rails is applied to control voltage output so that the run power state power rail is maintained within more precise constraints than the low power state power rail.

Abstract: A power supply input circuit includes an input node configured to removeably couple to an electrical source. A solid state switch is coupled between the input node and a capacitive load. An RC soft start circuit is coupled to the input node and the switch. The soft start circuit has a capacitor that causes the switch to increasingly pass electrical power from the source to the load as the capacitor charges from the source. An active reset circuit is coupled to the soft start circuit. The reset circuit is configured to detect when the source is removed from the input node and in response to the source being removed from the input node, the reset circuit discharges the capacitor to reset the soft start circuit.
