Abstract
Current absorption management for an electronic fuse coupled between an electrical supply source node and an electrical load node selectively controls a high current electronic switch and a low current electronic switch coupled in parallel between the electrical supply source node and the electrical load node. The high current and low current electronic switches are alternatively actuated: in a first mode where the high current electronic switch is turned on and the low current electronic switch is turned off, and in a second mode where the high current electronic switch is turned off and the low current electronic switch is turned on. Change to the second mode may be made in response to a standby state or a sensing of a lower current in the electrical load. Conversely, change to the first mode may be made in response to a sensing of a higher current in the electrical load.
