Abstract
An electronic circuit and a method are disclosed. The electronic circuit includes a first supply node and a second supply node configured to receive a supply voltage, an input configured to receive an input signal, and an output configured to be coupled to a control node of a transistor device. The electronic circuit further includes an undervoltage lockout (UVLO) circuit configured to perform a comparison of the supply voltage and a UVLO threshold. The electronic circuit is configured to operate in one of a first operating mode or a second operating mode based on the comparison. The UVLO circuit is configured to generate the UVLO threshold based on the supply voltage, and the electronic circuit is configured to generate the output signal, in the first mode, dependent on the input signal and to generate the output signal, in the second mode, in a predefined fashion independent of the input signal.
