Abstract

A power monitor circuit method delays the start of a computer until multiple power lines are at a safe level of operation. The integrated circuit monitors only the voltage of a primary power supply output and eliminates the need for monitor on each supply. The power supply is made to exacting specifications that tie the 5 volt and 3.3 volt supplies to the primary 12 volt supply. The ATX power supply drives the 3.3 and 5.0 supplies to reach 90% of their values within 40 ms after the 12 volt supply reaches 90% of its value. A time delay circuit 25 delays switching the 3.3 and 5 volt dual supply from the standby voltage supply to the active voltage supply until after the primary 3.3 and 5 volt are at a safe operating level.

It belongs to the difference between a human computer and an ancient brain: Λ-Γ, the circuit monitors and Control the supply of electricity to electricity such as a microprocessor: To = Shao :: such as memory, τ, and other parts ^ & to be different voltage. To save power, extend the integrated U'L't computer does not work The power available to the component is reduced when compared to the following: the 'seven knives, the computer has an on-predetermined time and the reduced power: power saving function. The operator can control the -time. When the power is deactivated, σ takes a lower power Send to the computer. In theory, when the user feels that it is necessary to recover the full power only when it is needed, it is reasonable to provide sufficient power. Ignore the building "4 degrees each" a There is still sufficient time to use It is necessary to supply electricity to its operational level. If the computer starts to operate before it is supplied to its level, the computer work and operation performed by the computer may be wrong. Such early operation can lead to operational problems. The error caused the Failure and downtime, then: the need to restart the computer or may need to be repaired. The power management function can provide the computer with the full efficiency of the operation, saving electricity to reduce costs. When the personal computer has become more sophisticated, t And: The monitoring circuit for Force V is also precise. The computer needs more because of using a variety of package pressure (fine electricity. The initial voltage used in the computer is 12 volts, 5 volts and 3.3 volts. From an AC / The DC converter is supplied to other settings and chips in the computer. In this way, the motherboard of the computer still needs a step-by-step driving voltage for the operating memory chip, the edge map chip and the clock chip. However, all These driving voltages are driven by three starting voltages of 12, 5, 3, and 3 volts. 4.

Description of the Invention 2) The two main points are that the computer manufacturer regulates many settings to do many settings: power on or power off. Unless power plus and power off operation are controlled under the nine feet < power, important information may be It can be lost or the system can collide with itself. For proper operation, the three starting voltages must be 90% or higher than their expected and operating levels. The seller of microprocessors, For example, Intel Corporation, the specifications for microprocessors and motherboards indicate that they will be fully operational after a predetermined time window. The time window is set to approximately 100 milliseconds. In order to assist the personal computer manufacturer Intel specification 3.3 and A 5 volt supply must f 40 milliseconds to reach ninety percent of it. The g faced by computer manufacturers is to make a decision on how to monitor the starting voltage when a voltage driven from the starting voltage is established. Some manufacturers provide monitoring chips that use three power supplies, one for each starting voltage. This is a straightforward approach, increasing the number of power supply monitors only to match the three starting voltages. Some others have suggested that a single chip be used to monitor the power supply and three start voltage monitoring circuits having a circuit on each single chip including two start voltages. ^ The invention improves the known solution by providing a time-integrated circuit with a single monitor with a single input voltage pin. The invention achieved this desired result by using an inherent feature of electricity supply. The voltage supply can indeed meet the specifications. This specification connects 5 volts and 3.3 volts to a 12 volt supply. The voltage supply will drive 3.3 and 5.0 supplies to 90% of its voltage within 40 milliseconds after 12 volts reaches 90% of its voltage.

Description of the invention (6-1): Circuit 22 is introduced to the power monitoring integrated circuit 20, which is more crying: resistance division wiring includes resistance to ㈣, as shown in the figure, the gross resistance is sufficient to make the voltage to compare Device 22 _ within the range of supply voltage. 妗 λ $ u Α is in 5 units of standby ik # ^ ^ The voltage VREF that is fed to the comparator 24 is driven by 5 = power supply. The set maximum reference voltage level is nine. 10. That is, ninety percent of 12 volts, etc. In her specific embodiment, the reference voltage is about ⑽ and the electric control is 106 volts and the 9-k divider. So, when it is connected across the resistance ruler 2 is special, The input to the comparator is equal and the input at the terminal 27 of the comparator is high. It indicates that the voltage Vi2 is about 90% of the mark. The high signal at the terminal 2 7 is transmitted to the drive voltage through the control line 3 2. The way: The high output of comparison state 24 is delayed by a timing delay circuit 25. The signal indicates that the power supply for 5, 3.3 and 2.5 volts is now a suitable level for generating a driving voltage for use. Remove, go to Figure 3, point out the progress of the invention-a description of the The supply voltage is supplied to the motherboard and the warp line 301 is monitored. This line provides an input-to-voltage divider (not shown, see Figure 2). The Qiu-Makeup device includes an internal Monitoring integrated circuit 22. The power monitoring integrated circuit M package, a timing circuit (not shown, see Figure 2) is used to determine the time from when the 12 volt supply equals or exceeds ninety percent of its marked value. This time is shorter than the 100 milliseconds used for the motherboard. When the timing circuit time is up, the control logic 304 controls the transistors Q2, q3, (54 and 〇5 to operate from the power supply of 10.5 volts and 3.3 volts. The second line is switched from the respective standby voltage to the line voltage. Circuit 22 has been simplified to Acci compliance in the microprocessor and computer applications.

Description of the invention (7) Line. Circuit 22 integrates two linear controllers and a low-current through transistor, as always on 16-pin Monitoring and control functions in SOIC components. A linear controller 305 The 3.3V DUAL voltage plane generated by the 5VSB output of an ATX power supply is in the rest state S3, S4 / S5. As indicated by the state of the 3.3V DUAL allowable pin, the PCL window is added through an external transistor The voltage is applied. An external transistor is used to switch the PCL operation to ATX 3.3 volt output during S 1 and S 1 (action) operation. The second linear controller 306 is supplied with electricity through an external transistor in an active state. 2.5V / 3.3V memory power of the steroid system. In S3 state, a product supplies 2.5V / 3.3V rest state power through a transistor. A third controller 307 is powered by the ATX 5V output in the active state or switched to the 5V DUAL plane by the ATX 5VSB in the inactive state. The operating mode of the circuit 2 2 (active state output or resting state output) is controlled by the two control pins 319 and 3 18, and the further control of the logic 304 allows the pins 319 and 320 to adjust the action of providing different power modes. . In the active state, the 3.3V DUAL linear regulator 305 uses an external N-channel to connect to the output 314 (V OUT 1) through the MOSFET transistor 331. When at the lowest loss, it is directly powered by an ATX (or equivalent) power supply Supply to 3.3 Volt Input. In the resting state, the 3.3V DUAL output is supplied by an ATX 5VSB 3 12 via an NPN transistor, or it can be externally applied to the controller. The active state delivers power to the 2.5 / 3.3 Volt MEM output via an external NPN transistor 332 or one of the NMOS semiconductor switches used for 3.3 Volt setting. In the quiescent state, an output path is switched to an external pass transistor. 5 V DUAL output 3 52 is supplied by two external MOS semiconductors.

Description of the invention (Pause state, a PM0S (or NPN) semiconductor; 333 is connected to the current by the aTX 5 VSB output. When in In the active state, the current passes through the converter to an NMOS semiconductor 334 and is connected to the ATX 5 volt output. As with the 3 3 V DUAL output, the operation of the 5 V DUAL output 352 is not only caused by the complaints of the 317 and 318 pins. The command can also be commanded by EN5VDL allowing pin 319. A 5 VSB power-on reset (P0R) signal initiates a soft-start state procedure. An internal 10 microamp current source charges an external capacitor to 5 volts. Error amplifier The reference input clamp is proportional to the level of the soft-start pin voltage. When the soft-start pin voltage is cut off from about 125 to 25, the input clamp increases a fast and controlled output voltage. Figure 4 shows the soft-start sequence, which is used for standard applications in a rest state and where all output voltages are allowed. 5 VSB (bias voltage) is added to the circuit. At time T 1,5VSB exceeds the FOR level, and an internal fast charging circuit quickly raises the voltage of the 58 capacitor to the next 1 volt. At this point '-1 10 microamps The current power source continues to charge the capacitors up to T 2. When the voltage of 1.25 volts (standard) is reached and an internal clamping limit is used for further charging. The charging of the soft-starting voltage (during the period from 2 to 3) should pay attention to the capacitor It is smaller than 0.1 microfarad. The soft-starting capacitor of 1 microfarad and a value higher than this indicates that a soft-starting saka degree is an invalid hand saka. At time T 3, 3 milliseconds (after 5VSB P 〇R (T1) standard), 丨 〇 The micro-ampere current power source charges the soft-start capacitor again. At this point, the reference input of the error amplifier initiates its transfer, causing the output voltage to rise in proportion to it, and the rise continues until all Time T 4 when the voltage reaches the set value. At time T 5, when the value of the soft-start capacitor reaches about 2 · 8 volts, the low-voltage monitoring circuit operates and soft-starts ------------ -------- Order --------- line (Please read the precautions on the back before filling this page) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs-11- 484050 Λ7 H7 9 V. Description of the invention (the value obtained by quickly discharging the moving capacitor to time D2 (approximately! 1 is volts). Such as 317 and 318—in time When 5VSB is added, it is logic high.

The characteristic of this time is necessary to ensure the stability of the output of the master Δτχ. When this time is reached, it can also maintain a smooth transition from rest to activity. When switching from quiescent to active state, the output is the initial 0 volt condition (for example, S4 / S5 to S0, EN3VDL = 1 and EN5VDL = 0 transition, or a single voltage addition program directly enters the active state), 3V DUAL and 5V The DUAL output is connected via a quasi-soft starter via an N-channel MOSFET transistor to the boosted body diode between its output and 3.3 V and 5 V ATX outputs. Figure 5 shows this explanation. When the output of the main ATX is turned on at time D0, 5VSb has appeared. Similarly, the soft-start capacitor has been charged to 125 volts and clamped for activity. Wait until the 12 volt POR timing is completed. As a result, 3 3V claws and 5V IN Ascending, the 3 DUAL and 5V DUAL output capacitors C1 & C3 are charged by their respective body diodes Q3 and Q5 (see Figure 3). At time T1, the U volt Δτχ output exceeds the circuit 2 2 H 2 volt low voltage threshold and the internal 50 millisecond (standard) timer 2 $ is started (Figure 2). At the time of T2, a soft-start is started, and the memory output rises, reaching the adjustment limit at time T3. At the same time, the memory voltage rises, the DLA output 321 is raised high (to 12 volts) to turn on 卩 3 and (^ 5), and at time T2, the 3.3V DUAL and 5V DUAL outputs are added to the adjustment value.
