Abstract

See full text

A high-side semiconductor-switch driving method includes generating power for controlling a high side semiconductor switch. The high side semiconductor switch has a control terminal and the power allows a current to flow into the control terminal of the high side semiconductor switch to switch the high side semiconductor switch. The voltage at the control terminal of the high side semiconductor switch is quantified. The power dependent on the voltage at the control terminal of the high side semiconductor switch is controlled so that the current provided is increased when the voltage at the control terminal indicates that the current is not sufficient to switch the high side semiconductor switch.
