Patent ID: 11870428
Assignee: INFINEON TECHNOLOGIES AUSTRIA AG
Field: Basic communication processes (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 14:
15. A circuit for controlling current through a transistor, the circuit comprising:
a voltage measurement circuit configured to measure a voltage across the transistor;
a current measurement circuit configured to measure a current through the transistor; and
a controller circuit configured to:
determine a safe operating current based on the voltage measured across the transistor;
adjust, for each of a first sequence of current pulses, a voltage of a voltage pulse applied to a control node of the transistor until the current measured through the transistor is not greater than a first function of the safe operating current; and
adjust, for each of a second sequence of current pulses after the first sequence of current pulses, the voltage of the voltage pulse applied to the control node of the transistor until the current measured through the transistor is not greater than a second function of the safe operating current.
