Especially, it is boost signal that described start drives signal, when described shutdown driving signal is low level signal.
Especially, described the second input end is electrically connected CPU heat alarm end, and when CPU was overheated, CPU heat alarm end sent shutdown and drives signal to the second input end.
Especially, be connected time-delay and negative circuit between described power switch and the described first input end.
Especially, be connected anti-phase module between described power source management controller and the second input end.
Compared with prior art, deenergization behind the off signal of the utility model power source management controller second output terminal in receiving D type flip-flop, electronic installation shuts down but also connects under the power supply status, the electric power of D type flip-flop only is provided, and no longer provide the electric power of power source management controller, the power consumption of D type flip-flop is less than the power consumption of power source management controller, therefore, and comparatively power saving.
[description of drawings]
Fig. 1 is the circuit diagram of the utility model power supply front end monitoring apparatus.
[embodiment]
See also shown in Figure 1, the utility model provides a kind of power supply front end monitoring apparatus, it is located in the electronic installation, and described power supply front end monitoring apparatus comprises D type flip-flop 10, power switch 20, power source management controller 30, and described D type flip-flop 10 comprises first input end 11, the second input end 12 and output control terminal 13; And when first input end 11 is in enabled status, output control terminal 13 output starting-up signals; And when the second input end 12 is in enabled status, output control terminal 13 output off signals; Described power switch 20 is electrically connected described first input end 11, and described power switch 20 sends start and drive signal to first input end 11 when pressing, and at this moment, first input end 11 is in enabled status; Described power source management controller 30 is electrically connected described power switch 20, the second input end 12 and output control terminal 13, and described power source management controller 30 detects and sends shutdown driving signal to the second input end 12 when carrying out power-off operation, at this moment, the second input end 12 is in enabled status, plugged behind the described power source management controller 30 reception starting-up signals, deenergization behind the power source management controller 30 reception off signals.
In present embodiment, it is boost signal that described start drives signal, when described shutdown driving signal is low level signal.Described the second input end 12 is electrically connected CPU heat alarm end 60, and when CPU was overheated, CPU heat alarm end 60 sent shutdown and drives signal to the second input end 12.Be connected time-delay and negative circuit 40 between described power switch 20 and the described first input end 11.Be connected anti-phase module 50 between described power source management controller 30 and the second input end 12.
