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.
