The invention discloses a resetting circuit with high reliability and ultra-low power consumption. The resetting circuit comprises a resetting circuit body, a resetting circuit arbitration unit and a power source rising detecting circuit, wherein the resetting circuit is a resetting circuit body of a chip; the resetting circuit arbitration unit is a resetting circuit enabled control signal arbitration center and generates enabled control signals of the resetting circuit body according to relevant signals; the power rising detecting circuit is used for detecting a rising edge of a power source; and when the rising edge is generated, an end Q of a trigger DFF1 (D-type flip flop) can output high level. On the basis of the resetting circuit body, the power source rising detecting circuit and the resetting circuit control arbitration unit are added; and when the chip is electrified, the resetting circuit body can be started no matter when POR-ENB is high level or low level, normal electrification setting of the chip is guaranteed, and resetting reliability of the chip is guaranteed.
