摘要： A charging circuit with an application system thereof provides an error amplifier to control a transistor switch for controlling the charging power source to charges the battery. When the voltage difference between the power source and load terminals of the transistor switch drops along with the transistor switch being turned on, the output voltage of the error amplifier changes as well to increase the turning-on resistance of the transistor switch such that the voltage difference between the power source and load terminals is capable of maintaining at a value above a certain reference level for avoiding the unstable state resulting from the charging circuit being turned on and off frequently.

摘要： A fast start-up low-voltage bandgap reference voltage generator uses two current generators to provide a first current having a positive temperature coefficient and a second current having a negative temperature coefficient, respectively, and a resistor to generate a temperature independent output voltage according to the sum of the first and second currents. The current generator for providing the first current has a self-bias circuit which uses a single MOSFET to establish the first current, and thereby avoids error caused by mismatched MOSFETs.

摘要： A power management control circuit controls a first power transistor to convert a input voltage to an output voltage and controls a second power transistor to charge a battery from the output voltage. The first power transistor is coupled between the input voltage and the output voltage, and the second power transistor is coupled between the output voltage and the battery. The power management control circuit includes: a detection transistor detecting a current through the second power transistor and generating a charging reference voltage; an amplifier comparing the output voltage with the voltage of the battery to generate an amplified signal for controlling the charging reference voltage; a comparator comparing a reference voltage with the charging reference voltage to generate an EOC (End of Charge) signal for determining whether to stop charging the battery; and an offset voltage compensation device compensating an input offset voltage of the amplifier.
