  • Circuit and method of over-current protection
    Patent number: 11005253
    Abstract: A method of over-current protection includes: determining a current flowing through a first element to be protected, comparing the determined current with a plurality of thresholds, controlling a counter based on the comparing the determined current with a plurality of thresholds, and stopping the current flowing through the first element by activating a switch in series with the first element when an output of the counter reaches a predetermined counter threshold.
    Type: Grant

  • Method for driving a transistor device and electronic circuit
    Patent number: 9712147
    Abstract: Disclosed is a method and a drive circuit. The method includes measuring a frequency of an input signal received by a drive circuit and driving a transistor device by the drive circuit based on the input signal such that a switching speed of the transistor is dependent on the measured frequency. The drive circuit is configured to receive an input signal, to measure a frequency of the input signal, and to drive a transistor device based on the input signal such that a switching speed of the transistor is dependent on the measured frequency.
