ABSTRACT:
In a voltage converter with a high-side short-circuit protection before an input voltage provided by a high-voltage power supply reaches a first threshold, a driver detects the input voltage and the output voltage of the converter to turn on the low-side transistor of the converter and turn off the high-voltage power supply when the input voltage ranges between the first threshold and a second threshold and the output voltage reaches a third threshold, to thereby avoid damages to the circuit connected to the output node of the converter. The driver comprises a front-end drive circuit to switch the high-side and low-side transistors and a low-voltage logic control circuit for the turning-on of the low-side transistor.
