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: The image sticking erasing circuit includes a detection circuit and a switching circuit connected to the detection circuit. The detection circuit is for use in detecting a first voltage signal, which closely follows the variation of the voltage source, and a reference voltage, which loosely follows the variation of the voltage source. When the detection circuit determines that the first voltage signal is lower than a first threshold value, the switching circuit switches the gate of a driving transistor to a second voltage signal, which loosely follows the voltage source. When the detection circuit determines that the reference voltage signal is lower than a second threshold value, the switching circuit switches the gate of a driving transistor to a low voltage state.
