Abstract: A system for prognosis and control of a power module includes a gate driver circuit and a controller circuit. The gate driver circuit drives a target gate node of a target power transistor in response to a pulse width modulation signal, measures a target gate voltage, switches a desaturation signal in response to the target power transistor switching between an off state and an on state, measures a target transistor voltage, and measures a target transistor current. The controller circuit modulates the pulse width modulation signal to increase the target gate voltage, determines a target threshold voltage as the target gate voltage in response to the desaturation signal switching states, determines a target on-resistance based on the target transistor voltage and the target transistor current, and controls the target power transistor based on the target threshold voltage and the target on-resistance.

Abstract: A system and method for receiving, at a multi-chip power module, multiple electronic control signals by one or more semiconductor devices of a first device type configured in parallel to one or more semiconductor devices of a second device type. The one or more semiconductor devices of the first device type and the one or more semiconductor devices of the second device type form a plurality of functional switches. The functional switches independently change states, in response to the plurality of electronic control signals. The one or more semiconductor devices of the first device type are configured to be electrically controlled for use independently and de-coupled, or in parallel, with the one or more semiconductor devices of the second device type.
