Description

Technical Field

[0001] The embodiments of the present application relate to the field of computers, and in particular, to a state control device, method and apparatus for a circuit fuse device. Background Art

[0002] With the development of server technology, the hard disk, as an important component of the server, has higher and higher performance and reliability requirements. In the prior art, the power supply reliability of the hard disk is the basic condition to ensure its normal operation. The EFUSE (Electronic Fuse) on the hard disk is activated when the input voltage is low to protect the hard disk from damage. However, this design has some problems. Specifically, the enable signal EN of the EFUSE in the prior art is obtained by the voltage division of the input voltage. When EN reaches its threshold voltage, the EFUSE starts working.

[0003] There are several key problems in the prior art. First, when the input voltage is low, EFUSE will start working, which may cause the EUFSE on the power supply board to be protected, resulting in power failure. Second, during the power failure process, EFUSE may output voltage again, resulting in non-monotonic power failure, and may even cause the voltage state signal of the output voltage of EFUSE to become high again, resulting in false detection. Finally, if EFUSE works in auto retry mode, since EN is always present, the EFUSE module will continuously try to restart when protection occurs, which may cause the EUFSE module to burn out.

[0046] The embodiments of the present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0048] The present application proposes a state control device for a circuit fuse device. Before describing the optional embodiments of the present application, in order to better understand the inventive concept of the present application and the creativity of the present solution, the related technologies are first described:

[0049] As the main configuration of storage models, the performance of server hard disk is particularly important, and its power supply reliability is the basic condition for the normal operation of server hard disk. During the power-on process, the EFUSE on the server hard disk is activated when the input voltage is low, which will cause the EUFSE on the board that powers the server hard disk to be protected, resulting in power failure. Figure 1 It is a schematic diagram of the EFUSE circuit structure in the related art, such as Figure 1As shown, in the related art, the enable signal EN of the EUFSE (PU11) on the board is obtained by dividing the input voltage of P12V_INPUT. When EN reaches its threshold voltage, EFUSE (PU11) starts working. When the output voltage VOUT of EFUSE (PU11) reaches 90% of its input voltage VIN, the PG signal of EFUSE (PU11) outputs a high level to control the enable signal EN of the EUFSE (PU12 (POL)) on the server hard disk, so that PU12 (POL) starts working. However, since the enable signal P12V_INPUT_EN is obtained by dividing the input voltage P12V_INPUT, when the input voltage is low, EFUSE will start working, and the EUFSE on the board that powers its hard disk will be protected, thereby powering off. The enable signal EN is obtained by dividing the input voltage. During the power-off process, the output P12V_STBY will be output again, resulting in non-monotonic power-off, and even causing P12V_STBY_PG to become high again, causing false detection. At this time, if EFUSE is working in auto retry mode and EN is always present, the EFUSE module will keep trying to restart when protection occurs, which may eventually cause the EUFSE module to burn out.

[0050] In order to solve these problems, a state control device of a circuit fuse device is provided in this embodiment. Figure 2 is a structural diagram of a circuit fuse device according to an embodiment of the present application, such as Figure 2 As shown, a voltage input interface (VIN), a signal input interface (EN) and a voltage output interface (VOUT) are deployed on the circuit fuse device (EFUSE), the voltage input interface is connected to the server power supply, the voltage output interface is connected to the server storage device, a signal generator and a parameter adjuster are deployed on the state control device, a first voltage point (Vin-), a second voltage point (Vin+) and a signal output point (OUT) are deployed on the signal generator, the voltage input interface is also connected to the signal input interface through the signal generator, wherein the signal generator is used to detect that the voltage input interface is powered on. In this case, the target voltage at the first voltage point is set to a first threshold voltage, and when it is detected that the current point voltage at the second voltage point is greater than or equal to the target voltage, a target enable signal (high level P12V_INPUT_EN) is generated through the signal output point, wherein the circuit fuse device is set to be turned on when the target enable signal is received; the parameter adjuster is used to set the target voltage at the first voltage point to a second threshold voltage when it is detected that the signal output point has generated the target enable signal, wherein the second threshold voltage is less than the first threshold voltage.

[0051] As an optional solution, the signal generator is further deployed with a first voltage divider circuit, a second voltage divider circuit and a comparator, the voltage input interface is connected to the first voltage point through the first voltage divider circuit, and the voltage input interface is also connected to the second voltage point through the second voltage divider circuit, wherein,

[0052] The first voltage divider circuit is configured to set the target voltage at the first voltage point to the first threshold voltage when detecting that the voltage input interface is powered on;

[0053] The second voltage dividing circuit is used to control the point voltage at the second voltage point to be positively correlated with the interface voltage on the voltage input interface;

[0054] The comparator is used to detect the relationship between the point voltage at the second voltage point and the target voltage, and control the signal output point to generate a target enable signal when it is detected that the current point voltage at the second voltage point is greater than or equal to the target voltage.

[0055] Optionally, in this embodiment, Figure 3 Schematic diagram of a circuit of a circuit protection device according to an embodiment of the present application Figure 1 ,like Figure 3 As shown, the signal generator is also deployed with a first voltage divider circuit, a second voltage divider circuit and a comparator PU23, the voltage input interface (VIN) is connected to the first voltage point (Vin-) through the first voltage divider circuit, and the voltage input interface (VIN) is also connected to the second voltage point (Vin+) through the second voltage divider circuit, wherein the first voltage divider circuit and the second voltage divider circuit divide voltage through voltage divider resistors (R23-R28) and a diode (D21), and the first voltage divider circuit may be, but is not limited to, the circuit where R25-R27 is located. The second voltage divider circuit may be, but is not limited to, the circuit where R23 and R24 are located.

[0056] Among them, P12V_INPUT passes through the fuse F21 to R23 and R28. When the back-end circuit is short-circuited, the fuse quickly blows to provide protection. When P12V_INPUT increases to 3.3V, the voltage regulator diode D21 is turned on, and the voltage of VDD_D21 is clamped to 3.3V. At this time, the voltage of the reverse input terminal Vin- of the comparator PU23 is: Vin-=UR+=3.3*(R26+R27) / (R25+R26+R27);

[0057] The voltage at the positive input terminal Vin+ of the comparator PU23 is: Vin+=P12V_INPUT*R24 / (R23+R24);

[0058] The voltage of Vin+ maintains a linear relationship with P12V_INPUT and increases with the increase of P12V_INPUT. When Vin+=Vin-=UR+, the VOUT output P12V_INPUT_EN of the comparator PU23 is a high level (target enable signal).

[0059] As an optional solution, a voltage-stabilizing diode, a first resistor, a second resistor and a third resistor are deployed on the first voltage-dividing circuit, the voltage input interface is respectively connected to one end of the voltage-stabilizing diode and one end of the first resistor through a voltage clamp, the other end of the voltage-stabilizing diode is grounded, the other end of the first resistor is respectively connected to the first voltage point and one end of the second resistor, the other end of the second resistor is connected in series with the third resistor and is grounded, a field effect transistor is deployed on the parameter adjuster, and the field effect transistor is connected in parallel to the third resistor, wherein,

[0060] The voltage stabilizing diode is used to maintain the voltage at the voltage clamp at a target voltage when it is detected that the voltage input interface is powered on, wherein when the voltage at the voltage clamp is the target voltage, the target voltage at the first voltage point is the first threshold voltage;

[0061] The field effect transistor is used to place the third resistor in a short-circuited state when it is detected that the signal output point generates the target enable signal, wherein when the third resistor is placed in the short-circuited state, the target voltage at the first voltage point is the second threshold voltage.

[0062] Optionally, in this embodiment, if Figure 3 As shown, the voltage stabilizing diode, the first resistor, the second resistor and the third resistor are respectively: D21, R25, R26, R27. The field effect transistor is Q21. When P12V_INPUT_EN is at a high level, the MOS tube Q21 is driven to conduct and the resistor R27 is shorted. At this time, the reverse input terminal voltage Vin- of the comparator PU23 is:

[0063] Vin-=UR-=3.3*R26 / (R25+R26);

[0064] Since UR- is less than UR+, the comparator PU23 has a hysteresis function to prevent the output P12V_INPUT_EN from fluctuating back and forth between high and low levels due to fluctuations in the P12V_INPUT input voltage.

[0065] As an optional solution, a voltage state interface is further deployed on the circuit fuse device, and a state detector is further deployed on the state control device, and the state detector is respectively connected to the voltage state interface and the signal output point of the signal generator, wherein:

[0066] The voltage status interface is used to output a first status signal when the voltage output by the voltage output interface of the circuit fuse device meets the target power supply condition, and output a second status signal when the voltage output by the voltage output interface of the circuit fuse device does not meet the target power supply condition, wherein the first status signal is used to indicate that the power supply of the server storage device is normal, and the second status signal is used to indicate that the power supply of the server storage device is abnormal;

[0067] The state detector is used to detect the number of switching times of the signal output by the voltage state interface from the first state signal to the second state signal during the process of the voltage output interface supplying power to the server storage device, and to prohibit the signal output point of the signal generator from generating the target enable signal when the number of switching times is greater than or equal to the target number, wherein the circuit fuse device is configured to be turned off when the target enable signal is not received.

[0068] Optionally, in this embodiment, Figure 4 Schematic diagram of a circuit of a circuit protection device according to an embodiment of the present application Figure 2 ,like Figure 4 As shown, a voltage state interface (PG) is also deployed on the circuit fuse device, and a state detector is also deployed on the state control device. The state detector is respectively connected to the voltage state interface (PG) and the signal output point (OUT) of the signal generator.

[0069] Among them, when P12V_INPUT_EN is at a high level, the circuit insurance device (also known as the EFUSE execution module) PU21 starts to work, and the P12V_STBY voltage rises slowly. When the P12V_STBY voltage reaches a certain threshold, the output P12V_STBY_PG is at a high level (equivalent to the first state signal). However, when the EFUSE execution module works abnormally, it will output P12V_STBY_PG as a low level (equivalent to the second state signal), and the circuit insurance device receives the P12V_INPUT_EN signal transmitted by the signal generator, and controls the operation of the circuit insurance device according to this signal. When P12V_INPUT_EN is at a high level, P12V_STBY is output normally, and P12V_STBY_PG is at a high level. If the circuit insurance device works abnormally, P12V_STBY_PG becomes a low level.

[0070] The status detector (also known as PG monitoring and EN control module) monitors the status of the P12V_STBY_PG signal. When the P12V_STBY_PG signal changes from high to low, the counter will increase by 1. The status list of the counter is as follows Table 1:

[0071] Table 1

[0072] PG_IO falling edge times Q30 Q31 Q32 Q33 EN_IO 1 1 0 0 0 0 2 0 1 0 0 0 3 1 1 0 0 0 4 0 0 1 0 0 5 1 0 1 0 0 6 0 1 1 0 0 7 1 1 1 0 0 8 0 0 0 1 0 9 1 0 0 1 0 10 0 1 0 1 0 11 1 1 0 1 0 12 0 0 1 1 0 13 1 0 1 1 0 14 0 1 1 1 0 15 1 1 1 1 1

[0073] Note: 1 represents high level output, and 0 represents low level output.

[0074] When the falling edge of PG_IO (ie, P12V_STBY_PG) reaches 15 times, the output EN_IO is high.

[0075] EN_IO controls the gate level of MOS tube Q22. When EN_IO is at a high level, MOS tube Q22 is turned on, making P12V_INPUT_EN at a low level, thereby turning off the EFUSE execution module (equivalent to prohibiting the signal output point of the signal generator from generating the target enable signal).

[0076] The state detector receives the P12V_STBY_PG signal from the circuit fuse device and monitors the falling edge of the signal. Each time the falling edge of the P12V_STBY_PG signal occurs, the counter in the state detector increases by 1. When the count reaches 15, EN_IO outputs a high level. The state detector transmits the EN_IO signal to the signal generator. Figure 5 is a schematic diagram of a counter in a state detector according to an embodiment of the present application, such as Figure 5 As shown, FF30, FF31, FF32, and FF33 are T flip-flops, and their 1T input terminal is 1. When the CL terminal signal is detected to change from high level to low level, the counter increases by 1. Four T flip-flops form a counter. When the count reaches 15, Q30, Q31, Q32, and Q33 output high level, and their signals generate EN_IO as high level after passing through the AND circuit.

[0077] The method embodiments provided in the embodiments of the present application can be executed in a server device or a similar computing device. Taking running on a server device as an example, Figure 6 1 is a hardware structure block diagram of a computer device of a circuit fuse device state control method according to an embodiment of the present application.
