Abstract
Apparatuses and circuits for overcurrent protection are described. A circuit can be connected to one of a first hybrid switching device and a second hybrid switching device in a half bridge circuit. The first hybrid switching device can include a first wide-bandgap (WBG) device and a first FET in a cascode arrangement. The first WBG device can have a higher breakdown voltage than the first FET and a larger band gap than the first FET. The second hybrid switching device can include a second hybrid switching device including a second WBG device and a second FET in a cascode arrangement. The second WBG device can have a higher breakdown voltage than the second FET and a larger band gap than the second FET. The circuit can monitor a drive current of the half bridge circuit for detecting an overcurrent condition of the half bridge circuit.
