摘要: An exemplary method for controlling a charging current is adapted to a charging device. The charging device receives an input voltage to thereby output the charging current. The method includes the following steps of: making the charging current have a first value; judging whether the input voltage is less than a preset reference voltage; and if the input voltage is judged to be less than the preset reference voltage, decreasing the charging current from the first value step by step until the input voltage retrieves back above the preset reference voltage.

摘要: The present invention discloses a charge control circuit for supplying power from an external power source to a first common node and charging a second common node from the first common node. A regulator circuit is coupled between the external power source and the first common node, and a transistor is coupled between the first common node and the second common node. The present invention detects an operation parameter of the transistor and controls an internal voltage source to generate a non-predetermined voltage difference accordingly. When the sum of the voltage at the second common node and the non-predetermined voltage is equal to or higher than the reference voltage, the voltage at the first common node is regulated to a level higher than the voltage at the second common node, and the transistor is in an optimum conductive state.

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 power safety system includes a first MOS, a second MOS, a switch and a body controller. The first MOS is connected between a power input and a power output. The second MOSFET is connected between the power output and a charging output. The switch has an end connected to the body of the first MOS, and the opposite end switched between the source and the drain of the first MOS. A body controller controls the switch according to the voltage at the power input and the voltage at the power output, to connect the body of the first MOS to the source or the drain of the first MOS. By switching the switch, the first MOS will have a parasitic diode effective to prevent a reverse current from the power output to the power input.

摘要: An automatic switch method and apparatus are used to set the output current of a USB by slowly increasing the output current under monitoring the voltage on the USB. If the USB could normally operate until the output current reaches a threshold value, a higher level is set for the output current, otherwise a lower level is set instead. The process may be performed periodically to dynamically determine the output current for the USB.
