摘要： The present disclosure includes circuits and methods for cable resistance compensation. In one embodiment, the present disclosure includes a circuit comprising a regulator coupled to receive an input voltage and an input current from an external power source across a cable, a voltage sensor coupled to sense the input voltage, a collapse detector coupled to detect whether or not the input voltage is below a first value, and a current limit circuit to control a maximum current in the regulator. The current limit circuit is reconfigured to a plurality of current limit values and the collapse detector detects if the input voltage from the external power source collapses below the first value at the plurality of current limit values. The voltage sensor measures different voltages at different input currents, and in accordance therewith, reduces collapse voltage value to compensate for a voltage drop caused by a resistance of the cable.

摘要： Multiple power chargers for mobile terminals (10) are disclosed. In particularly contemplated aspects, a mobile terminal may include two charging circuits (34, 36) 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 (80) 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 (40). The system power node is further tied to a top port (66) of the second charger. A bottom port (72) of the second charger is tied to a top port (74) of the first charger. A bottom port (82) of the first charger is tied to the battery (38) 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.
