Quick turn off of contactor system during power off

A method, comprising:

• detecting that a supply voltage of a contactor system is less than a threshold voltage in response to a determination that quick-turn-off (QTO) is to be performed;
• disabling a high-side (HS) clamp of the contactor system;
• setting a QTO threshold voltage;
• determining that an output voltage of the contactor system is greater than the QTO threshold voltage;
• enabling charging of a low-side (LS) transistor of the contactor system;
• and
• performing QTO.

A system, comprising:

• a high-side (HS) transistor having first and second current terminals and a gate;
• a low-side (LS) transistor having first and second current terminals and a gate;
• a middle transistor having first and second current terminals and a gate, the second current terminal of the middle transistor coupled to the second current terminal of the HS transistor, and the first current terminal of the middle transistor coupled to the first current terminal of the LS transistor, the coupling of the first current terminals of the middle and LS transistors providing an output node of the system;
• a HS clamp coupled between the gate of the middle transistor and the output node, the HS clamp including a disable circuit having a supply voltage input, an output voltage input, and an output coupled to a switch-controlled current path between the first terminal of the middle transistor and the gate of the middle transistor;
• a LS clamp coupled between the gate of the LS transistor and the output node;
• and
• a control circuit having a supply voltage input, an output voltage input, and an output coupled to the LS clamp.
