Abstract: A method and device for thermal mitigation. The communications device including a first radio communications subsystem configured to operate according to a first radio communications protocol and a second radio communications subsystem configured to operate according to a second radio communications protocol. The first radio communications subsystem includes a temperature sensor and an electronic processor configured to determine, via the temperature sensor, a first temperature indicative of a temperature of the second radio communications subsystem, compare the first temperature to at least one predetermined temperature threshold, and deactivate the second radio communications subsystem when the first temperature exceeds a predetermined temperature threshold of the at least one predetermined temperature threshold.

Abstract: A device, method and system for throttling current and/or power to peripherals is provided. A device comprises peripherals powered by a power source. The device further comprises a throttling circuit configured to: in response to receiving a given interrupt, cause throttling of respective currents to a given subset of the peripherals. The device further comprises a sensing circuit configured to: in response to determining that a sensed current from the power source exceeds a threshold current, provide the given interrupt to the throttling circuit. The device further comprises a primary processor configured to: determine the threshold current based at least on a predetermined maximum current of a presently prioritized peripheral; and provide the threshold current to the sensing circuit. The device further comprises a secondary processor configured to: determine the given subset of the peripherals based on an available current overhead.

Abstract: A battery operated portable communication device (100) provides improved power up of converged functionality managed by a power arbitration module (PAM) (104), a baseband processor (BP) (108), and an applications processor (AP) (104). In response to a control switch (120) being turned on, the baseband processor generates a time delay and asserts a boot-line to the applications processor which prevents full power up of the applications processor and during which a battery impedance is read, thereby preventing simultaneous power up of the AP and BP. The boot-line from the baseband processor to the applications processor is released once the BP power up is complete and battery impedance is read.
