Such as, when the positive pole of the first electric capacity 1311 and negative pole electrically connect with the input of relay 125 and output respectively, increase along with power-on time, voltage between the positive pole of the first electric capacity 1311 and negative pole raises also with the increase of time, that is, the voltage between input and the output of the relay 125 electrically connected with first electric capacity 1311 the two poles of the earth raises along with the increase of power-on time.After exceeding Preset Time between upon power-up, when the voltage between relay 125 input and output exceedes conducting voltage threshold value, relay 125 is closed therewith, and the output impedance of on-off circuit 12 the most just switches to Low ESR from high impedance.And when entering power-down state between positive pole and the negative pole of the first electric capacity 1311, along with the electric capacity in load capacitance circuit discharges, the voltage between input and the output of load capacitance circuit is gradually lowered.After voltage between the input and output of load capacitance circuit falls below predeterminated voltage, first electric capacity 1311 starts electric discharge, voltage between positive pole and the negative pole of the first electric capacity 1311 also decreases, and the magnitude of voltage between relay 125 input and output also decreases.When magnitude of voltage between relay 125 input and output is reduced to below conduction threshold, relay 125 is disconnected therewith, and the output impedance of on-off circuit 12 the most just switches to high impedance from Low ESR.

As can be seen from the above analysis, on-off circuit 12 is switched to the Preset Time of Low ESR output state to be the time that the first electric capacity 1311 is charged to the conducting voltage of relay 125 or metal-oxide-semiconductor 121 by high impedance output state, namely the first electric capacity 1311 is charged to the time of preset voltage value.Further, the first different electric capacity 1311 charging intervals can be obtained by the parameter controlling the first electric capacity 1311 and pull-up resistor 1313, that is, obtain different control on-off circuits 12 to be switched to the low-impedance time by high impedance, that is, Preset Time.
Optionally, when on-off circuit 12 includes metal-oxide-semiconductor 121, can connect between the positive pole of the first electric capacity 1311 and the output of capacitive load circuit 11 and have the 3rd electric capacity 1321, for reducing the conducting electric current of metal-oxide-semiconductor 121.
Concrete, when the 3rd electric capacity 1321 and metal-oxide-semiconductor 121 are in parallel, total Muller electric capacity can be increased.The Muller plateau time of Vgs can be increased metal-oxide-semiconductor 121 is opened when, can slow down the decrease speed of Vds voltage, thus reduce metal-oxide-semiconductor 121 open electric current.Wherein, the pressure reduction between Vgs finger grid (G) and source electrode (S)；Vds refers to the pressure reduction between drain electrode (D) and source electrode (S).
Meanwhile, when the first electric capacity 1311 discharges, the 3rd electric capacity 1321 can also extend for first electric capacity 1311 discharge time, thus increases the service time of metal-oxide-semiconductor 121.
The power control circuit 1 of the present embodiment, by being connected on the first electric capacity 1311 between positive source 14 and power supply ground 15 and pull-up resistor 1313, on-off circuit 12 can be controlled by the discharge and recharge of the first electric capacity 1311 very easily to switch between high impedance output and Low ESR export, it is achieved that the automation of battery hot plug.And, the charging interval of the first electric capacity 1311 can also be controlled by the parameter adjusting the first resistance 123 and the first electric capacity 1311, thus control the time that on-off circuit 12 is switched to Low ESR to export by high impedance output, and then the time that when raising powers on, capacitive load circuit 11 charges under high impedance is to improve the effect of the anti-electric spark of power control circuit 1.
