The present application discloses a contactor coil control circuit, including a switch control circuit, a drive circuit, a fast turn-off circuit, a diode D1, a first MOS (Metal Oxide Semiconductor) transistor TR1 and a contactor coil. The fast turn-off circuit at least includes an MOS transistor TR2 or a triode; the cathode of the diode is connected to an input voltage VIN; the anode of the diode is connected to a first port of the fast turn-off circuit; a second port of the fast turn-off circuit is connected to the drain of the first MOS transistor; the source of the first MOS transistor is grounded; one end of the contactor coil L1 is connected to an input voltage, and the other end of the contactor coil is connected to the drain of the first MOS transistor; a third port of the fast turn-off circuit is connected to an output port of the drive circuit; an input port of the drive circuit is connected to a first output port of the switch control circuit; and a second output port of the switch control circuit is connected to the gate of the first MOS transistor. On the premise of turning off the contactor quickly, the coil control circuit is lower in loss, adopts a fewer of devices, and is lower in cost and smaller in volume.
