US Patent 11955957 Smart electronic switch

In accordance with an embodiment, a circuit for driving an electronic switch includes a control circuit configured to trigger a switch-on and a switch-off of the electronic switch in accordance with an input signal, wherein the control circuit is further configured to trigger the switch-off of the electronic switch in response to an under-voltage signal signaling an under-voltage state; and an under-voltage detection circuit configured to signal the under-voltage state when a supply voltage received at a supply node is below an under-voltage threshold value, wherein the under-voltage threshold value depends on a load current passing through the electronic switch.
