Abstract
A method and device for monitoring a multi-die power module in a half-bridge switch configuration are provided. The method and device are designed to set dies in a non conductive state, select one die which is blocking a voltage, inject a current in a gate of the selected die in order to charge an input parasitic capacitance of the selected die, monitor a voltage that is representative of a voltage on the gate of the selected die, and memorize the value of the monitored voltage when the value of the monitored voltage is stabilized.
