Current absorption management circuit, corresponding system and method

A circuit, comprising:

• a first node configured to be coupled to an electrical supply source;
• a second node configured to be coupled to an electrical load;
• a third node configured to be coupled to a control node of an electronic switch that is coupled between the electrical supply source and the electrical load;
• a secondary electronic switch coupled between the first node and the second node;
• control logic circuitry configured to provide a first switch control signal applied through said third node to the control node of the electronic switch for controlling switching of the electronic switch between a conductive state for delivering a first current level to the electrical load from the electrical supply source, and a non-conductive state;
• wherein said control logic circuitry is further configured to provide a second switch control signal applied to a control node of the secondary electronic switch for controlling switching of the secondary electronic switch between a conductive state for delivering a second current level to the electrical load from the electrical supply source, and a non-conductive state, wherein the second current level is lower than the first current level;
• wherein the first switch control signal and the second switch control signal control the electronic switch and secondary electronic switch such that, alternately:
• in a first mode of operation, the first switch control signal switches the electronic switch to the conductive state to deliver the first current level to the second node and the second switch control signal switches the secondary electronic switch to the non-conductive state;
• and
• in a second mode of operation, the first switch control signal switches the electronic switch to the non-conductive state and the second switch control signal switches the secondary electronic switch to the conductive state to deliver the second current level to the second node.
