Electronic spatial system

An electronic spatial system including:

• an electronic circuit sensitive to spatial radiations comprising at least one signal input port and/or at least one signal output port;
• a signal processing unit;
• an electronic unit for detecting spatial radiations electrically connected to the signal processing unit;
• at least one protective switch electrically connected between the electrical ground of the electronic spatial system and at least one out of the signal input or output ports of the sensitive electronic circuit, and controlled by the signal processing unit, the protective switch being configured to be switched from an OFF electrical state into an ON electrical state within a time period less than one hundred microseconds;
• at least one cut-off switch electrically arranged in parallel with the at least one protective switch, and controlled by the signal processing unit, and including a bipolar transistor configured to be switched from an OFF electrical state into an ON electrical state within a time period greater than one hundred microseconds,
• the signal processing unit being configured to switch the at least one protective switch to the electrical ground upon detection of an amplitude of a signal representative of the amount of spatial radiations greater than a predefined radiation threshold,
• the signal processing unit being configured to switch the cut-off switch to the electrical ground when turning off the sensitive electronic circuit.
