    摘要： Method and circuits for sensing a bidirectional current without requiring an external sense resistor are disclosed. In a preferred embodiment the invention is applied for fuel gauging of one or more batteries and comprises a charger/active diode, which can source current into the battery and sink current from the battery to supply a mobile electronic device. The invention can be applied to any other application requiring sensing of bidirectional currents. A regulated cascode forces a voltage drop over a power transistor and a sense transistor to be the same. A feedback current is measured by an ADC. The integration of these current measurements over time is equal to the actual charge of the battery.

    摘要： Circuits and methods for dynamic adjustment of the current limit of a power management unit to avoid unwanted automatic interruption of the power flow have been disclosed. The invention can be applied to switched and linear DC-to-DC converters. The power management unit is automatically adjusted to the output resistance of a power source (including interconnect resistance). The invention maximizes the time and hence the power transferred from a power management unit to the system (including the battery, in case of battery operated systems). The input current is reduced, thus increasing the input voltage in case of a high voltage drop across the internal resistance including interconnections between power source and power management unit.

    摘要： Circuits and methods to charge batteries of a portable device simultaneously with supplying power to the device for its operation, using a power source with limited maximum current, as e.g. an USB port, have been achieved. The system invented relies upon digital control only. No direct sensing of the current required for the operation of the portable device is required. The control takes care that the sum of the charging current and of the current to run the portable device does not exceed the maximum allowable current of the power source. The current required to run the portable device has precedence over the charging current.
