A system includes an electronic device including a circuit having a semiconductor switch, and a controller configured to control a gate driver connected to the semiconductor switch via a protection circuit. The controller is configured to set a protection parameter including a voltage threshold representing a selected value of a voltage across the semiconductor switch, the protection parameter configured to cause the semiconductor switch to be deactivated in response to an overcurrent condition, the protection parameter selected based on a mathematical model of the semiconductor switch, the mathematical model representing a physical property of at least one of the electronic device and the semiconductor switch.

Electronic control of protection parameters for a semiconductor switch

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.
