Abstract
In some implementations, a method of dynamically maintaining a device's operation within a safe operating area (SOA) may include sensing instantaneous voltage and current of the device; determining, based on the sensed instantaneous voltage and current, a value that represents a power dissipated in the device; using the determined dissipated power and a model of thermal behavior of the device to model a junction temperature of the device; and controlling operation of the device based on the modeled junction temperature. A programmable SOA circuit including sensing, scaling, filtering, and controlling functions may be packaged on a single die or in a package with a power transistor.
