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.
