Abstract: The present disclosure includes a method of charging a battery. In one embodiment, the method comprises receiving, in a battery charging circuit on an electronic device, an input voltage having a first voltage value from an external power source. The battery charger is configured to produce a charge current having a first current value into the battery. The input current limit and/or duty cycle of the charger is monitored. Control signals may be generated to increase the first voltage value of the input voltage if either (i) the input current limit is activated or (ii) the duty cycle reaches a maximum duty cycle. The charger also receives signals indicating a temperature inside the electronic device and generates control signals to decrease the value of the input voltage when the temperature increases above a threshold temperature.

Abstract: Over-voltage protection systems and methods are disclosed. In one aspect, a biasing circuit is added to a pre-existing clamp required by the Universal Serial Bus (USB) Type-C specification at a configuration control (CC) pin. The biasing circuit turns the pre-existing clamp into an adjustable clamp that dynamically adjusts to over-voltage conditions. In an exemplary aspect, the biasing circuit may include a biasing field effect transistor (FET) and a pair of switches that selectively couple the pre-existing clamp and the biasing FET to fixed voltages such that the CC pin is maintained at an acceptable voltage. In another exemplary aspect, the biasing circuit may omit the biasing FET and rely on two switches that selectively couple the pre-existing clamp to fixed voltages such that the CC pin is maintained at an acceptable voltage.

Abstract: A multi-phase (e.g., dual-phase) concurrent configuration of a power management component supports higher current levels to peripheral devices while maintaining acceptable thermal limits. A dual-phase integrated circuit (IC) having a first input/output (I/O) port coupled to a battery and a second I/O port coupled to an adapter and a peripheral device implements the configuration. The dual phase IC includes a dual-phase voltage regulator that selectively provide power (i) from the first I/O port to the second I/O port to provide power to the peripheral device or (ii) from the second I/O port to the first I/O port to provide power to the battery. A controller activates a boost phase to power the second I/O port in response to detecting a demand current of the peripheral device exceeds a maximum current available from the adapter.

Abstract: Systems, methods, and apparatus for testing devices adapted for connection to other devices using universal serial bus (USB) are disclosed. Devices to be tested are caused to enter a special mode of operation when resistance measured at one or more terminals of a USB Type-C connector have values associated with the special mode of operation. One or more operations of the device are automatically initiated when the resistance coupled to the at least one terminal of the connector has a measured value that matches one of a set of resistance values maintained by the device. The one or more operations may include configuring a power management circuit based on the measured value, and entering a mode of operation that controls startup of at least one processor on the device when the measured value matches a first resistance value.

Abstract: Systems, methods, and apparatus for testing devices adapted for connection to other devices using universal serial bus (USB) are disclosed. Devices to be tested are caused to enter a special mode of operation when a resistance measured across two terminals of a USB Type-C connector has a value associated with the special mode of operation. One or more operations of the device are automatically initiated when the resistance between the two terminals has a measured value that matches one of a set of resistance values maintained by the device. The one or more operations may include configuring a power management circuit based on the measured value, and entering a special or factory boot mode that controls startup of at least one processor on the device based on the measured value. Each of the set of resistance values exceeds a minimum open-circuit resistance value specified for the connector.
