Three triode Q3 are NPN triode.The grid of described first FET Q1 connects the colelctor electrode of the 3rd triode Q3, the most logical
Cross the drain electrode that the second resistance R2 connects the first FET Q1；The drain electrode of the first FET Q1 connects external power source 3V3 end, goes back
Connected the colelctor electrode of the second triode Q2 by the first resistance R1, the source electrode of the first FET Q1 connects MINI PCIE female seat
3V3 end；The base stage of described second triode Q2 connects output and the insertion of MINI PCIE female seat inserting detection module 40
Test side (i.e. HPD end), the colelctor electrode of the second triode Q2 by the 3rd resistance R3 connect the 3rd triode Q3 base stage, second
The grounded emitter of triode Q2；The base stage of described 3rd triode Q3 passes through the first electric capacity C1 ground connection, the 3rd triode Q3's
Grounded emitter.The drain electrode of the first FET Q1 is i.e. the first end 1 of the first on-off circuit, and the base stage of the second triode Q2 is i.e.
Being the control end 2 of the first on-off circuit, the source electrode of the first FET Q1 is i.e. the output 3 of the first on-off circuit.Second opens
Close the circuit structure within circuit and the first on-off circuit is identical, the difference is that only that the first of second switch circuit is defeated
Enter end 1, its output 3 and connect external power source 5V end, the 5V end of MINI PCIE female seat respectively.As a example by the first on-off circuit, when
When HOTPLUG signal is high level, the second triode Q2 conducting, the 3rd triode Q3 cut-off, the 3.3V on external power source 3V3 end
Voltage cannot be by the 3V3 end of the first FET Q1 transmission to MINI PCIE female seat, and the voltage of UD_3V3 is low level.
When HOTPLUG signal is low level, the 3rd triode Q3 conducting makes the first FET Q1 conducting, and the voltage of UD_3V3 is
Voltage 3.3V on external power source 3V3 end, then the 3V3 end input 3.3V voltage of MINI PCIE female seat.The work of second switch circuit
Making principle identical with the first on-off circuit, simply second switch circuit transmission is 5V voltage.
Described insertion detection module 40 is used for judging whether upgrading subsystem module 20 accesses TV and produce corresponding
HOTPLUG signal, it includes the 4th resistance R4 and the 5th resistance R5, please refer to Fig. 2 A, the processor of main system module 10
Include that mainboard processes chip U4.One end (i.e. inserting the output of detection module 40) of described 4th resistance R4 connects at mainboard
Reason the GPIO mouth of chip U4, the 4th end 4 of USB handover module 50, the 4th end 4 and MINI PCIE female seat of SD handover module 60
Insertion test side.The other end of the 4th resistance R4 connects external power source 3V3 end；One end of 5th resistance R5 connects the 4th resistance
The output of one end of R4, i.e. insertion detection module 40, the other end ground connection of the 5th resistance R5.When MINI PCIE male seat does not has
When inserting MINI PCIE female seat, the output inserting detection module is driven high by the 4th resistance R4, exports HOTPLUG signal
For high level.Now the first on-off circuit and second switch circuit are in closed mode.When MINI PCIE male seat inserts MINI
During PCIE female seat, the output inserting detection module is pulled low by the 5th resistance R5, and the HOTPLUG signal of output becomes low electricity
Flat.Now the first on-off circuit and second switch circuit are opened, and the first electric capacity C1 in Fig. 3 starts to charge up, the 3rd triode Q3
Can postpone a period of time just becomes high level and turns on, the source electrode output 3.3V/5V voltage of the first FET Q1.First switch
Circuit and second switch circuit play and insert the function postponing power supply, i.e. during MINI PCIE male seat insertion MINI PCIE female seat also
Not power supply at once, but just powered by the first on-off circuit and second switch circuit delay a period of time, so can be true
Protect and just indirectly power to upgrading subsystem module 20 after MINI PCIE male seat is plugged completely, improve the security of system.
It is that the present invention has the electricity of USB handover module in the TV of hardware configuration upgrade function please refer to Fig. 5, Fig. 5
