Abstract: Thermal mitigation features may be included in a Universal Serial Bus (USB) cable assembly or in the USB receptacle portion of a device. In one aspect, one or both ends of a USB cable jacket may have greater thermal conductivity than the portion between them. The portion having the greater thermal conductivity may dissipate excess heat from the cable into the environment. In another aspect, a USB cable connector or the USB receptacle portion of a device may include a thermoelectric heat pump. The thermoelectric heat pump may move excess heat from the cable assembly or receptacle into a portion of the cable assembly or device that dissipates the heat into the environment.

Abstract: An apparatus is disclosed for adaptively providing power. In example implementations, an apparatus includes a power adapter coupler, at least one transistor, a first charger, and a second charger. The first charger and the second charger are coupled between the power adapter coupler and the transistor. The apparatus also includes a first switch, a second switch, and a charging controller. The first switch is coupled in series with the first charger between the power adapter coupler and the transistor. The second switch is coupled in series with the second charger between the power adapter coupler and the transistor. The charging controller is coupled to the first switch and the second switch. The charging controller is configured to selectively close the first switch to connect the first charger to the at least one transistor or close the second switch to connect the second charger to the at least one transistor.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for supplying power, including battery charging. One example power supply circuit generally includes a switching regulator including an output node, a first power supply node coupled to the output node of the switching regulator, a first charge pump including a first terminal coupled to the first power supply node and including a second terminal coupled to a second power supply node, a first battery node for coupling to a first battery, and a first switch including a first terminal coupled to the first power supply node and including a second terminal connected to the first battery node.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for supplying power, including battery charging. One example power supply circuit generally includes a switching regulator including an output node; a first battery node for coupling to a first battery; a second battery node for coupling to a second battery; a first switch coupled between the output node of the switching regulator and the first battery node; and a second switch coupled between the output node of the switching regulator and the second battery node. Such a power supply circuit may independently control and monitor the charging of multiple independent batteries without using multiple chargers, may balance the batteries during discharging, and may operate without a current limit switch.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for charging a device. Some example methods for charging a device generally include providing power from a first device to a second device, the second device being configured for electrical connection with the first device via a cable. For example, a method may include transmitting a signal comprising one or more parameters associated with the first device to the second device, receiving a signal at the first device via a pin designated for a configuration channel, the signal indicating at least one of a requested charging voltage or a requested charging current based on the one or more parameters, and outputting power from the first device to the second device based on the signal.

Abstract: A first portable or non-portable device enters an adaptive charging mode to deliver a programmable output voltage to a second (e.g., sink) device, independent of a connector between the devices. The adaptive charging mode enables a sink device to detect current and voltage capability of the portable or non-portable device. It is determined whether a first device coupled to the second device through a reconfigurable port is configured as a source device or sink device. A current limit of the source device is then detected. A programmable voltage from the source device is requested based on the detecting.
