An electronic circuit breaker for a vehicle, comprising: an input configured to be connected to a DC power supply; an output configured to be connected to a load; said input connected to said output via a semiconductor switch with a linear region of operation, and a saturated region of operation, said semiconductor switch comprises a switch control input; a switch driver configured to control the semiconductor switch and comprising a switch control output; wherein said switch control output is connected to the switch control input via a pre-charge circuit comprising a turn-'ON' branch which is configured to cause the semiconductor switch to operate in the linear region of operation during turn-“ON”; and a turn-“OFF” branch which is configured to cause the switch to turn-“OFF”.

Electronic circuit breaker for a vehicle, and a method therefor

An electronic circuit breaker comprising: an input connected to an electric DC power supply; an output connected to a load; the input connected to the output via a switch, said switch is controlled via a switch control line between an 'ON'-state and an “OFF”-state; a switch driver connected to the switch control line, said switch driver configured to control the switch; and a switch protection, a voltage detection branch configured to output a first electric potential indicative of the electrical potential difference between the input and the output; a comparator circuit configured to compare the first electrical potential with a first threshold voltage, said first threshold voltage is indicative of an over-current level flowing through the switch; and a gate controller connected to the switch disable line and configured to disable the switch by connecting the switch control line to a potential which causes the switch to enter the “OFF”-state.
