摘要： The present application discloses various implementations of a power management unit (PMU) suitable for use in a mobile device. In one exemplary implementation, such a PMU includes a gain control block configured to control an oscillator coupled to the PMU. The gain control block is further configured to control a clock output stage of the PMU. The PMU also includes a signal protection circuit coupled to an input of the gain control block. The signal protection circuit is configured to preserve clock signals produced by the clock output stage during a transition to a standby mode.

摘要： There are disclosed herein various implementations of a power management system for powering a portable device while charging a multi-series-cell battery of the portable device when the portable device is connected to an adapter. One exemplary implementation comprises a voltage regulator for powering the portable device and a multi-mode charger receiving input power from the adapter. The multi-mode charger is operated in a switching mode for charging the multi-series-cell battery concurrently with the voltage regulator powering the portable device. In another implementation, the power management system is adapted for use with a portable device having a single-cell battery.
