摘要： A method and apparatus for adjusting transmission power in a portable two-way radio device allows the device to determine an expected battery voltage drop for a subsequent transmit event, based on present transmit power settings and battery impedance, and change the power setting for the subsequent transmit event if the battery voltage is likely to drop below a shutdown threshold at the present power setting or if the expected battery voltage drop will cause the battery voltage to be substantially above the shutdown voltage level and the present power setting is below an optimal level.

摘要： Systems and methods for supplying power from a multi-cell battery to a single-cell power management integrated circuit. One implementation of the system includes a voltage converter circuit, a control circuit, and a signal buffer circuit. The voltage converter circuit is configured to scale a positive battery terminal voltage signal received from the multi-cell battery to generate a scaled voltage signal. The control circuit is configured to select one of the scaled voltage signal or a cell voltage signal received from the multi-cell battery. The control circuit is also configured to output a high-impedance single-cell power signal including the selected one of the scaled voltage signal or the cell voltage signal. The signal buffer circuit is configured to buffer the high-impedance single-cell power signal to generate a low-impedance single-cell power signal for a voltage sense pin of the single-cell power management integrated circuit.

摘要： 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.

摘要： Systems and methods for determining available current for a battery in a portable electronic device. One method includes, in response to determining that a received current level of an auxiliary supply rail is equal to or below a predetermined threshold, acquiring a plurality of unloaded voltages for the battery and calculating an unloaded voltage based on the unloaded voltages. The method includes activating a switchable load coupled between the battery and ground, acquiring a plurality of loaded voltages for the battery, and calculating a loaded voltage based on the loaded voltages. The method includes calculating an impedance for the battery based on the unloaded and loaded voltages and an impedance for the switchable load. The method includes determining a current budget based on the impedance, a minimum operating voltage, and a maximum allowable current draw, and adjusting an operating parameter of the portable electronic device based on the current budget.

摘要： A method and apparatus for mission critical standby of a portable communication device are disclosed. A portable communication device may include a primary processor for a first operating platform, a secondary processor for a second operating platform and communicatively coupled to the primary processor, and a power state manager that may have a first mode and a second mode. The power state manager may be configured to determine whether the primary processor is in a powered off state and sequence supply of power to the secondary processor. The first mode may allow the primary processor to monitor a power state of the secondary processor based on a determination that the primary processor is not in the powered off state and the second mode may enable the power state manager to monitor the power state based on a determination that the primary processor is in the powered off state.

摘要： A battery operated portable communication device provides converged functionality while avoiding resets to the device. Composite logic circuitry formed of at least one comparator and a logic interface controls current limiting to a primary load formed of high power land mobile radio (LMR) devices and programming to secondary loads formed of non-LMR peripherals. At least one current limit control signal is used to control current to the primary load under high current mode operations. Another control signal provides an interruption alert to a slave processor for controlled programming of the secondary loads during the high current operations of the primary load. Current to the primary load is restored while the secondary load is interrupted. Operation of secondary load processes is resumed when the primary load ceases high power operation.

摘要： Method and system for maintaining output voltage regulation of a non-synchronous switching regulator providing a voltage supply to a main load. The method includes determining, using an electronic processor, that the main load is transitioning from a first load state to a second load state. The method also includes connecting, using the electronic processor, a switchable load to the non-synchronous switching regulator in response to determining that the main load is transitioning from the first load state to the second load state.
