Abstract: Multiple power chargers for mobile terminals are disclosed. In particularly contemplated aspects, a mobile terminal may include two charging circuits arranged serially, such that only one charging circuit charges a battery of the mobile terminal at a time. The serial arrangement allows consolidation of fuel gauge circuitry within one of the charging circuits. In a particularly contemplated aspect, a second charger is tied to a first charger at a system power node. The system power node is further tied to a top port of the second charger. A bottom port of the second charger is tied to a top port of the first charger. A bottom port of the first charger is tied to the battery of the mobile terminal. The fuel gauge circuitry may sense battery current using a known ON resistance of a field effect transistor (FET) of the first charger.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for wireless communication. In certain aspects, the apparatus generally includes a first interface configured to obtain, from a baseband module, a multiplexed signal comprising a control signal, a second interface configured to obtain a power signal, a radio frequency (RF) module, a regulator coupled to the second interface and configured to receive the power signal, and a circuit configured to provide the control signal to the regulator. In certain aspects, the regulator, in response to the control signal, may be configured to generate a supply voltage signal by regulating the power signal and provide the supply voltage signal to the RF module.
