Electronic protection device for an electrical load, power supply system for an electrical load and method for controlling such a device

An electronic device for protecting an electrical load against an overcurrent of an electrical current, the electronic device comprising:

• an arrangement of at least one transistor designed to be connected in series with the load, the arrangement of at least one transistor comprising two conduction poles and a control pole and being controllable, via its control pole, into a state out of an on state in which the current circulates between the conduction poles, and an off state in which the current does not circulate between the conduction poles, the off state being from among a first off state and a second off state;
• a current sensor configured to measure an intensity of the current intended to circulate through the load;
• a control module connected to the current sensor and configured to control the arrangement of at least one transistor via its control pole, the control module being configured to control the arrangement of at least one transistor into its second off state if the intensity of the current, measured by the current sensor, is above a first intensity threshold;
• and
• a voltage sensor connected to the control module, and configured to measure a voltage between the conduction poles of the arrangement of at least one transistor,
• wherein the control module is further configured to control the arrangement of at least one transistor into its on state from its first off state if the voltage between the conduction poles, measured by the voltage sensor, is above a voltage threshold;
• and into its first off state if the intensity of the current, measured by the current sensor, is below a second intensity threshold, distinct from the first intensity threshold.
