摘要：
The present invention concerns a method and a device for monitoring a multi-die power module (15) comprising dies that are in a half-bridge switch configuration.
The invention:
- sets the dies in a non conductive state,
- selects one die which is blocking a voltage,
- injects a current in a gate of the selected die in order to charge an input parasitic capacitance of the selected die,
- monitors a voltage that is representative of a voltage on the gate of the selected die,
- memorizes the value of the monitored voltage when the value of the monitored voltage is stabilized.
