For the boot-strap circuit that illustrates that further the embodiment of the invention provides, it is as follows now in conjunction with Fig. 2-Fig. 5 in detail its principle of work to be described in detail:
After acquiescence was plugged AT power supply or ATX power supply, the hard switching of power interface circuit 1 was open-minded, if use this moment is the AT power supply, then 5VSB, 12VSB power on, and PSON# is drawn on the resistance R 1 to be high level signal; If the ATX power supply, then 5VSB powers on, and PSON# also is a high level signal.
As shown in Figure 4 and Figure 5, when PSON# is high level, NPN type triode Q5, NPN type triode Q6 conducting, NMOSFETQ3, NMOSFETQ4 end, PMOSFETQ1, PMOSFETQ2 end, and what no matter use is AT power supply or ATX power supply, and 12V and 5V do not have voltage at this moment.
If what use before start is the AT power supply, 12VSB should have voltage so, if use is the ATX power supply, 12VSB does not have voltage so, thereby can be with 12VSB as the power supply type judgment signal; But this signal can not directly be brought as the power supply type signal, because can instead be poured into 12VSB at ATX power supply start back 12V, causes the erroneous judgement of signal disconnected.
In power supply type testing circuit 2, d type flip flop U2A plugs moment by 12VSB differentiation power supply type and with this signal latch at power connection.Because start 5VSB in service is rising edge for once, thereby the output PWR_AT of trigger and PWR_AT# just no longer change obtain signal in the 5VSB uphill process after, guaranteeing that afterwards 12VSB voltage changes can not influence PWR_AT and PWR_AT#, that is to say that power supply type finished in power supply hard switching conducting moment.For the data input pin D input signal that guarantees d type flip flop U2A has enough Times Created, 5VSB gives Schmidt trigger U1A, Schmidt trigger U1B after being postponed by resistance R 2 and capacitor C 1, be latched to the first output terminal Q at the data input pin D input signal of CLK signal building up transient d type flip flop U2A.If the AT power supply, then PWR_AT is output as 1, and PWR_AT# is output as 0; If the ATX power supply, then PWR_AT is output as 0, and PWR_AT# is output as 1; PWR_AT is sent to the Enable Pin EN_3.3V of 3.3V voltage transformation module, if the AT power supply, then EN_3.3V is output as 1, and expression allows successive plates to carry the switching motion of 3.3V power supply, otherwise forbids the 3.3V switching motion.PWR_AT also can be sent to BIOS, closes input switch in order to remind the user.
The power on mode of AT power supply is just start of mainboard after the hard switching conducting of power supply, and the power on mode of ATX power supply to be mainboard wait for after the user is by the button on the lower case starts shooting.Starting-up signal produces circuit 3 and oneself produce a low pulse signal under the situation of AT power supply, waits for that under ATX power supply situation button triggers a low pulse signal.Starting-up signal produces in the circuit 3 or the signal of the first input end of door U4A is administered the break-make of single-shot trigger circuit 31 output signals, during signal, can pass through when PWR_AT# is 0, and the low pulse signal of promptly starting shooting can be produced by single-shot trigger circuit 31; During signal, can not pass through when PWR_AT# is 1, the low pulse signal of promptly starting shooting must be produced by start switch SW 1.Signal for the first input end input of or door U4A stable to time enough, after postponing, PWR_AT process resistance R 3 and capacitor C 2 give single-shot trigger circuit 31, single-shot trigger circuit 31 is exported a low pulse signal when U1C receives the rising edge trigger pip, as the starting-up signal under the AT electric source modes.In case when the low pulse signal input being arranged, will send a low pulse signal PWRBTN# with the output terminal of door U5A with the first input end of door U5A or second input end.
Start sequential circuit 4 has comprised interface control chip SIO and south bridge SB, interface control chip SIO sends the IO_PWRBTN# low pulse signal to south bridge SB after receiving the PWRBTN# low pulse signal, the high level of the SLP_S3# signal of south bridge SB output is afterwards given interface control chip SIO, and interface control chip SIO after receiving the SLP_S3# signal drags down the PSON# signal.
The PSON# signal is sent back to power interface circuit 1 (being the 1st pin of ATX power interface 14), if the ATX power supply will directly be exported 12V, 5V, 3.3V; If the AT power supply, the metal-oxide-semiconductor Q1 conducting in the 12V power switch circuit, the metal-oxide-semiconductor Q2 conducting in the 5V power switch circuit, input 12V and 5V voltage, plate carries the work of 3.3V modular converter simultaneously, and output 3.3V voltage is finished boot action.
The boot-strap circuit that the embodiment of the invention provides detects the type of power supply by the power supply type testing circuit, starting-up signal produces circuit according to detected power supply type output low pulse signal, the start sequential circuit is exported 12V, 5V and 3.3V power supply according to low pulse signal, the mainboard start; Solved AT power supply and the ATX power supply intelligent compatibling problem on mainboard effectively, changing power supply does not need wire jumper, for the mainboard user brings convenience in the use; Solved the problem of pressure drop that adopts the diode mode to bring simultaneously, and the sequential under the strict control AT electric source modes, its pattern in strict accordance with the ATX power supply is powered on.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
