Current control type contactor driving circuit and device integrated with boost function

The invention provides a current control type contactor driving circuit and device integrated with a boost function, and the circuit comprises a DC power supply and an integrated driving circuit, the integrated driving circuit comprises a boost unit and a driving unit, the driving unit comprises a contactor coil, and the driving unit and the boost unit share a part of devices; the input end of the direct-current power supply is electrically connected with the integrated driving circuit; the boosting unit can work independently to boost the DC power supply; when the boosting unit and the driving unit work at the same time, the current of a contactor coil is controlled on the basis of realizing a boosting output function, and large-current suction and low-current maintenance of the contactor are realized; and when the contactor needs to be turned off, the coil current of the contactor is quickly reduced through the back voltage provided in the circuit, so that the quick turn-off and energy recovery functions ar
