Driver circuit for initialization of output signal for switch-on and switch-off of electric consumer, has field-effect transistor with gate connection and output for initialization of output signal to electric consumer

摘要

The driver circuit (100) has a field-effect transistor (160) with a gate connection and an output for initialization of an output signal to electric consumer (110). The driver circuit has a comparing unit (210) with one input (210b) for receiving of gate voltage and another input (210c) for receiving an output voltage of the output signal. The comparing unit is formed to determine whether gate voltage and output voltage fulfill a pre-determined connection to each other and to provide control signal at float circuit (170) in such a manner, that if predetermined connection is fulfilled, the change current if changing is changed in amounts in comparison to a changed current of changing if predetermined connection is not fulfilled.
