Abstract

A circuit for preventing shoot-through in a high side switching transistor coupled in series with a low side switching transistor across a supply voltage, the circuit comprising a voltage reference circuit having an output providing a reference voltage which is negative with respect to the supply voltage provided to the high side switching transistor, the reference voltage being applied to the control electrode of the high side switching transistor when the high side switching transistor is off and the source of the high side switching transistor exceeds the reference voltage and the low side switching transistor is on.
