ABSTRACT:
A battery charger integrated circuit with temperature control is disclosed that includes a temperature sensor circuit and a charging current generator circuit. Upon receiving a temperature reading voltage (VDT), the temperature sensing circuit is operable to generate a second reference voltage (VREF) that is a function of the first reference voltage (VREF1). The charging current generator circuit generates and continuously adjusts a reference current (I1) and a charging current (IOUT) according to the second reference voltage (VREF). Whenever the temperature reading voltage (VDT) exceeds the first reference voltage, the temperature sensor circuit is operable to adjust the second reference voltage (VREF).
