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 portable battery operated communication device provides a device interface formed of a plurality of exposed device contacts including a live voltage contact and a GND contact. Electronic circuitry associated with the interface is configured to operate in a non-linear mode using a low leakage path in response to electrolytic contamination across the two contacts. The interface is further configured to operate in a linear mode using a low current path during accessory attachment. Accessory detection is provided by a non-linear impedance device and sensor.
