摘要： A circuit and a method for providing a switchable current linkage between a first terminal and a second terminal is presented. The circuit has a transistor switch and a charge pump circuit An output node of the charge pump circuit is coupled to a control terminal of the transistor device, and an input node of the charge pump circuit is coupled to a predetermined voltage. The charge pump generates a boosted voltage. A drive circuit provides feedback control for the current flowing through the transistor. The drive circuit also controls the voltage magnitude at the input node of the charge pump circuit in accordance with the feedback control or to control a magnitude of a voltage at the control terminal of the transistor device in accordance with the feedback control.
