Patent ID: 8917118

Claim:
A circuit arrangement comprising a driver circuit configured to generate a control signal at a high voltage and at a low voltage for driving a power switch; wherein the driver circuit comprises a voltage regulator configured to generate a second voltage from a supply voltage; a drive unit configured to generate the control signal based on the supply voltage and configured to provide the control signal to a control interface of the driver circuit; and a logic component operating at the second voltage and drawing a second current, and configured to control the drive unit; and a bypass circuitry coupled at an input to the control interface and configured to provide at an output at least part of the second current to the logic component, when the control signal is at high voltage; wherein the driver circuit comprises a plurality of drive units configured to generate a plurality of control signals for a plurality of power switches, respectively, and configured to provide the plurality of control signals to a plurality of control interfaces of the driver circuit, respectively; and the circuit arrangement comprises a plurality of bypass circuitries, each coupled at an input to a respective control interface and each configured to provide at an output at least part of the second current to the logic component.
