Beschreibung
Zusammenfassung:	A system and method of over-voltage protection includes a switch coupled between a power source and a load, a detection circuit configured to detect an onset of an over-voltage event at the load; and a driver circuit coupled to the switch and the detection circuit. The driver circuit includes a boost sub-circuit that provides a low-resistance path for opening the switch in a boost mode, the boost mode being triggered by the onset of the over-voltage event and having a predetermined duration and a steady state sub-circuit that provides a high-resistance path for holding the switch open during steady state operation when the boost mode.
