Abstract: A consumer electronic device includes a battery module and a system chip. The battery module includes: battery cells, a heater adjacent to the battery cells, a battery management circuit coupled to the battery cells and the heater, and an electrical connector including an information transmission interface and a power transmission interface. The information transmission interface is coupled to the battery management circuit, and the power transmission interface is coupled to the battery cells. The system chip is coupled to the information transmission interface, and is configured to receive battery information from the battery management circuit through the information transmission interface. When a battery temperature of the battery information is lower than a first threshold, the system chip sends an activation signal to the battery management circuit through the information transmission interface, for the battery management circuit to activate the heater according to the activation signal.

Abstract: A control method of a power delivery device includes communicating with a power adaptor through a configuration channel pin of a connector to acquire a power supply quota of the power adaptor and generate a power consumption threshold based on the acquired power supply quota, selecting a corresponding scenario mode from a plurality of scenario modes according to a scenario setting signal generated by a setting circuit when a total power consumption of a system circuit is greater than the power consumption threshold, selecting a corresponding exclusion parameter from a plurality of exclusion parameters according to the corresponding scenario mode, excluding a corresponding power-down procedure from a plurality of power-down procedures according to the corresponding exclusion parameter to generate a selected power-down group, and performing at least one power-down procedure in the selected power-down group to reduce the total power consumption.

Abstract: A control method of a power supply path includes detecting a plug-in state of a first connector through a configuration channel pin of the first connector; acquiring a plurality of rated voltages of a first power adaptor externally connected to the first connector and a rated current corresponding to each of the rated voltages; detecting a plug-in state of a second connector through a direct-current (DC) input pin of the second connector; acquiring a power quota of a second power adaptor externally connected to the second connector; selecting, from the plurality of rated voltages, the largest one that is not greater than an operating voltage, as a selected rated voltage; calculating a power quota of the selected rated voltage; and controlling a switching circuit to couple a power circuit to a power pin of one of the first and second connectors according to the two power quotas.

Abstract: A touch device includes a touch sensing unit, a processing unit, an embedded controller and a digital controller. The touch sensing unit has a first control mode and a second control mode, and senses a touch event from a touch stylus. The embedded controller is coupled to the processing unit. The digital controller is coupled to the touch sensing unit, the embedded controller and the processing unit, and receives a general-purpose input/output (GPIO) signal from the embedded controller. When the GPIO signal is in a first value, the digital controller reports the first control mode to the processing unit. When the GPIO signal is in a second value, the digital processor reports the second control mode to the processing unit. Thus, the performance of the touch device and the touch stylus is improved.
