摘要： A communication method includes detecting at a gate drive unit a change of state of a command signal that is received via a command link of the gate drive unit and initiating, responsive to the change of state of the command signal, a blanking period in which the gate drive unit will process as incoming data any further changes of state of the command signal. The method also includes receiving incoming data at the gate drive unit, by processing modulations of the command signal, within the blanking period.

摘要： A method for reducing thermal cycling of a semiconductor power switch includes obtaining a value indicative of a junction temperature of the power switch. The method also includes selecting one of several pre-determined gate drive voltages, based on the obtained value, and providing the selected gate drive voltage to a gate of the power switch. This reduces thermal cycling of a power switch relative to the thermal cycling that would be present during operation at a single gate voltage.

摘要： A power switch current estimator for a solid state power switch. The power switch includes a control terminal, an input current power terminal, and an output current power terminal. The power switch is further configured with at least one sense terminal. One or more parasitic elements define an electrical pathway between a power terminal and a corresponding sense terminal. A driver unit that selectively turns the power switch on and off is connected to the control terminal and a sense terminal. A current estimator generates an estimated level of current circulating through the solid state power switch in real time in response to one or more switching events of the power switch. The estimated level of current is based on values of at least one of the parasitic elements such that the estimated level of load current substantially corresponds to an actual level of load current circulating through the solid state power switch.
