[0051] In recent years, with the rapid progress of artificial intelligence, 5G communication and new energy technology, power management chips are facing increasingly complex and challenging demands and challenges. The high standards of artificial intelligence chips for power consumption and heat dissipation require power management chips to provide more efficient and stable power conversion and management functions. Higher data transmission rates and greater energy consumption requirements further test the stability and reliability of power management chips. Therefore, under the dual driving of technology and market demand, power management chips must continue to progress and develop.

[0052] For power management chips, a wide input voltage range can enable the chip to meet the needs of different input voltages, improve the flexibility of the system, and be applicable to different scenarios. Lower input voltage requirements can effectively avoid system confusion when the battery power is about to run out, improving system stability. Lower input voltage can also improve the utilization rate of the battery and reduce dependence on external power supply, reducing system cost.

[0053] In a wide piezoelectric power management chip, the traditional starting circuit usually adopts the series connection of a current-limiting resistor and a clamping diode to output a clamping voltage of 5.5V at most, which is used to control the conduction of a high-voltage NMOS transistor, and the output of the high-voltage NMOS transistor is the output of the starting circuit. In the traditional architecture, the minimum input voltage required by the power management chip is equivalent to adding a high-voltage NMOS transistor conduction voltage to the output voltage of the starting circuit. With the increase of the input voltage withstand voltage value, the withstand voltage level of the high-voltage NMOS transistor also increases, resulting in an increase in the conduction voltage. According to the PVT simulation results, it is found that the conduction voltage of the high-voltage NMOS transistor can be up to 1V or more, which accounts for a large proportion of the minimum input voltage value. Therefore, in order to further reduce the input voltage, the conduction voltage of the high-voltage NMOS transistor needs to be considered.

[0054] In the present application, the starting voltage is divided into two branches. One branch is the same as the traditional starting circuit, which is responsible for initially pulling up the internal circuit and providing an initial voltage. The other branch is combined with the loop of the bandgap reference to transmit the input voltage to the output without pressure difference under low input voltage condition, further reducing the minimum input voltage required by the chip.

[0055] In view of at least one of the technical problems existing in the prior art, embodiments of the present application provide a driving circuit device, a control method, equipment, a medium and products, so as to provide a starting circuit architecture for normal work under lower input voltage condition and meet the power supply demand of wide input power voltage range, and realize better stability of power supply effect under various working conditions such as high and low voltage and high and low temperature.

[0056] The following will be based on the technical problems of the existing capacitor type driver as shown in Figure 1, and through FIGS. 1A-3 The driving circuit device of the disclosed embodiment is described in detail.

[0057] FIG. 1A A circuit module composition diagram of the driving circuit device 100 according to the embodiment of the present application is schematically shown. FIG. 2 A circuit specific composition diagram of the driving circuit device according to the embodiment of the present application is schematically shown.

[0058] As FIGS. 1A-3 shown, an aspect of the embodiment of the present application provides a driving circuit device 100, which comprises a starting circuit module 101 and an auxiliary pull-up module 102.

[0059] The input end of the starting circuit module 101 is connected with an input signal V IN , and the output end of the starting circuit module 101 is connected with a load.

[0060] The auxiliary pull-up module 102 is connected to the input terminal of the startup circuit module 101.

[0061] When the auxiliary pull-up module 102 receives the enable electrical signal, it provides a pull-up electrical signal to the start-up circuit module 101, so that the start-up circuit module 101 adjusts the input electrical signal V according to the pull-up electrical signal and the input electrical signal V. IN The output electrical signal V at the output terminal of the start-up circuit module 101 OUT The circuit is pulled up until the target drive signal is output by the startup circuit module.

[0062] like FIG. 1A As shown, the input electrical signal V IN The output electrical signal V can be generated by the startup circuit module 101. OUT The power signal is used to power the startup circuit module 101, so that the startup circuit module 101 can output the target drive electrical signal.

[0063] like FIG. 1A As shown, in this embodiment of the invention, the startup circuit module 101 can serve as the initial startup path unit for the load, used to establish the output voltage under initial low input voltage conditions. The load can be the driving target of the drive circuit device (e.g., the power module of a power management chip), used to receive the target drive signal output after being pulled up by the auxiliary pull-up module 102. Therefore, the target drive signal can be the output signal V. OUT The output electrical signal after being stretched and stabilized. In this embodiment of the invention, the electrical signal can be an input or output voltage signal or a current signal, and there is no specific limitation.

[0064] The enable signal can be the operating signal of the auxiliary pull-up module 102. When the enable signal is applied to the input terminal of the auxiliary pull-up module 102, the auxiliary pull-up module 102 can provide a pull-up signal to the startup circuit module 101. The pull-up signal enables the startup circuit module 101 to respond to the input signal V. IN Under the condition of keeping constant, the output electrical signal V at the output terminal OUT The output electrical signal V is pulled up. OUT Approaching the input electrical signal V IN This reduces the pressure difference between the two. Therefore, even if the input electrical signal V... IN It can be small, but it can also output a large output electrical signal.

[0065] The target drive signal can be the standard drive signal of the load. Typically, the target drive signal is smaller than the input signal V. IN In other words, the magnitude of the target driving electrical signal is affected by the input electrical signal V. IN .

[0066] like FIG. 2 As shown, in this embodiment of the invention, when the startup circuit module 101 receives the input electrical signal V... IN When the gate voltage of the first N-type transistor MN1 in the startup circuit module 101 gradually increases, and the first N-type transistor MN1 is not turned on when the gate voltage does not exceed its threshold turn-on voltage, the current I... _MN1 The current is 0. The first N-type transistor MN1 turns on only when its gate voltage is greater than or equal to its threshold turn-on voltage, at which point the current I... _MN1 The input signal V gradually increases, and the starting circuit module 101 first enters the initial start-up stage T1. IN The increase of , output electrical signal V OUT It will also gradually increase, and at the input electrical signal V IN When the signal remains stable, the output electrical signal V OUT The circuit stabilizes and enters the pull-up triggering stage T2. In the auxiliary pull-up triggering stage T2, the auxiliary pull-up module 102 begins to receive an enable signal. As the enable signal gradually increases, the auxiliary pull-up module 102 is triggered and provides a pull-up signal to the startup circuit module 101, entering the auxiliary pull-up action stage T3. At this time, the startup circuit module 101 determines the activation status based on the pull-up signal and the input signal V. IN The dual effect of the output electrical signal V OUT The input electrical signal V is gradually increased again. IN and output electrical signal V OUT The pressure difference between them gradually decreases until the output electrical signal V is reached. OUT The preset value of the target drive electrical signal is met.

[0067] Therefore, compared to traditional technologies that cannot effectively balance small input voltages and large output voltages, the driving circuit device described in this embodiment of the invention, with the aid pull-up module 102, can assist in boosting the output voltage of the startup circuit module 101 under a small input voltage, thereby achieving a wider range of voltage output from the startup circuit module 101, through the output electrical signal V. OUT and input electrical signal V IN A smaller voltage difference between the components results in lower power consumption. This also allows for a further reduction in the minimum input voltage required by the chip, effectively preventing system errors when the battery is about to run out, improving system stability, reducing dependence on external power sources, lowering system costs, improving battery utilization, meeting different voltage requirements, increasing flexibility, expanding the application range, and having higher economic and practical value.

[0069] As FIGS. 1A-3 shown, according to an embodiment of the present application, the starting circuit module 101 comprises a first N-type transistor MN1, a first resistor R1 and a first clamping diode Z1.

[0088] As shown in FIGS. 1A-3 , according to an embodiment of the present application, the driving circuit device 100 further comprises a pull-up stabilizing module 103.

[0089] The pull-up stabilizing module 103 is connected to the input terminal of the auxiliary pull-up module 102, and inputs the start-up electrical signal to the auxiliary pull-up module 102.

[0090] As shown in FIG. 1BAs shown, the pull-up stabilization module 103 can output an enable signal, which is applied to the input terminal of the auxiliary pull-up module 102 (such as the gate of the sixth N-type transistor MN6 mentioned above).

[0092] FIG. 1C The diagram schematically illustrates another circuit module composition of the drive circuit device according to an embodiment of the present invention.

[0093] like FIGS. 1A-3 As shown, according to one embodiment of the present invention, the input terminal of the pull-up stabilization module 103 is connected to the output terminal of the startup circuit module 101 to receive the output electrical signal V of the startup circuit module 101. OUT .

OUT This serves as the electrical signal to activate the circuit.

[0095] Therefore, as FIG. 1C and FIG. 2 As shown, in another embodiment of the present invention, the startup circuit module 101 can serve as the initial startup path unit for the load, used as the initial low input voltage (i.e., input electrical signal V). IN The output voltage (i.e., the output electrical signal V) under the following conditions OUT The establishment of ) and the output of electrical signal V OUT It can also provide an initial operating voltage (i.e., an operating start signal) to the pull-up stabilization module 103, enabling the pull-up stabilization module 103 to output the aforementioned start signal as the initial operating voltage for the auxiliary pull-up module 102 (e.g., ...).

The auxiliary pull-up module 102 can output a pull-up electrical signal to the startup circuit module 101 accordingly, controlling the output electrical signal V. OUTThe pull-up boost, in turn, affects the operating voltage of the pull-up stabilization module 103, causing changes in the electrical signals generated by the auxiliary pull-up module 102 and the startup circuit module 101, until the output electrical signal V... OUT Maintain stability. The pull-up stabilization module 103 is mainly used to stabilize the output electrical signal V. OUT The feedback keeps the output of the pull-up electrical signal of the auxiliary pull-up module 102 stable, thereby avoiding an increase in the power consumption of the auxiliary pull-up module 102.

[0096] FIG. 3 The diagram schematically illustrates the timing waveforms of the voltage V and current I of a key circuit element in a drive circuit device according to an embodiment of the present invention.

[0097] like FIGS. 1C-3 As shown, before the initial start-up phase T1 of the circuit, the start-up circuit module 101 is connected to the input electrical signal V. IN The input electrical signal V IN The voltage gradually increases. When the gate voltage of the first N-type transistor MN1 exceeds its threshold voltage, the first N-type transistor MN1 turns on, thereby gradually increasing the output electrical signal V at the output terminal. OUT The circuit enters its initial startup phase T1. During this phase, the output electrical signal V... OUT The input voltage can be connected to the input terminal of the pull-up stabilization module 103, so that the actual operating voltage of the pull-up stabilization module 103 gradually increases and meets its preset operating voltage. When the pull-up stabilization module 103 generates an enable electrical signal V to be output to the auxiliary pull-up module 102. G_MN6 Then, enter the pull-up trigger phase T2.

[0098] During the pull-up trigger phase T2, the input electrical signal V is... IN and output electrical signal V OUT All remain stable for the time being. At this time, when the enable electrical signal V of the input auxiliary pull-up module 102 is applied... G_MN6 When the gate on-state voltage of the sixth N-type transistor MN6 of the auxiliary pull-up module 102 is gradually increased until it meets the requirements, the auxiliary pull-up module 102 starts working and enters the auxiliary pull-up action stage T3. Subsequently, the auxiliary pull-up module 102 outputs a pull-up electrical signal to the startup circuit module 102 through the eighth P-type transistor MP8 of the first current mirror, when the input electrical signal V... IN While maintaining stability, achieve the output electrical signal V OUT The signal is further pulled up and increased until it stabilizes at the target level to activate the electrical signal.

[0099] During the auxiliary pull-up phase T3, the auxiliary pull-up module 102 acts as a resistor to the output electrical signal V of the startup circuit module 101. OUTpull-up assistance. At this time, the gate voltage of the sixth N-type transistor MN6 is greater than its conduction voltage, and the branch of the ninth resistor R9 and the seventh P-type transistor MP7 of the first current mirror begins to have current flowing through it. At this time, the current of the seventh P-type transistor MP7 is copied through the first current mirror composed of the seventh P-type transistor MP7 and the eighth P-type transistor MP8, so that the current of the branch of the eighth P-type transistor MP8 increases, and the pull-up electric signal is output to the starting circuit module 101, thereby assisting the output of the output electric signal V OUT of the starting circuit module 101. At this time, the auxiliary pull-up module 102 formally starts to work. In the auxiliary pull-up phase T3, due to the rise of the output electric signal V OUT , the gate voltage of the sixth N-type transistor MN6 continues to rise through the pull-up stabilization module 103, the current of the branch of the ninth resistor R9 and the seventh P-type transistor MP7 continues to increase, so that the pull-up current I _MP8 (output pull-up signal) output by the eighth P-type transistor MP8 is further increased, and the output electric signal V OUT is continuously further pulled up. At the same time, due to the increase of the output electric signal V OUT , the gate-source voltage difference (the voltage difference between the gate voltage and the source voltage) of the first N-type transistor MN1 decreases, and the current I _MN1 flowing through the first N-type transistor MN1 continuously decreases. When the current I _MP8 of the eighth P-type transistor MP8 exceeds a certain value of the current I _MN1 of the first N-type transistor MN1, the pull-up current I OUT of the output electric signal V _MP8 is only provided by the current of the eighth P-type transistor MP8, and the entire driving circuit device will enter a stable stage and output a target driving electric signal.

[0100] The auxiliary pull-up module 102 is driven by the pull-up stabilization module 103 to start working when the output electric signal V OUT of the starting circuit module 101 is greater than the preset working voltage of the pull-up stabilization module 103, so as to replace the pull-up ability of the output node voltage of the starting circuit module 101, and further reduce the voltage difference V GS1 between the output electric signal V OUT and the input voltage (i.e., the input electric signal V IN ). In order to ensure that the voltage difference is smaller, the output electric signal V OUT and the input electric signal V INCloser, the voltage drop of the eighth P-type transistor MP8 is smaller than the threshold voltage of the first N-type transistor MN1 of the starting circuit module, so that when the eighth P-type transistor MP8 is stable to the starting circuit module 101, the first N-type transistor MN1 of the starting circuit module 101 can be basically in the off state (ideally I _MN1 Close to or equal to 0), by means of the current I _MP8 of the eighth P-type transistor MP8

[0101] Therefore, by means of the driving circuit device as shown in the above embodiment of the present application FIG. 1C and FIG. 2 , the interaction of the starting circuit module 101, the pull-up stabilization module 103 and the auxiliary pull-up module 102 can be realized, forming an electrical signal multiplexing with a cyclic feedback mechanism, which can ensure the stable output of the target opening electrical signal in a wider range under the stable input electrical signal, so that the target opening electrical signal is close to the input electrical signal, thereby further reducing the amplitude of the input electrical signal and reducing the driving power consumption.

[0139] In summary, in the initial stage T1 of the circuit, as the input voltage V IN Further increase the sum of the threshold voltages of the first N-type transistor MN1 of the start-up circuit module 101 and the second N-type transistor MN2 of the pull-up stabilization module 103, at this time the third resistor R3 and the branch of the first P-type transistor MP1 of the second current mirror start to have current flowing through. The second current mirror formed by the first P-type transistor MP1 and the second P-type transistor MP2 copies the current of the first P-type transistor MP1 to the branch of the second P-type transistor MP2, so that the branch of the second P-type transistor MP2 is turned on, thereby the pull-up stabilization module 103 starts to pull up the gate voltage of the sixth N-type transistor MN6 of the auxiliary pull-up module 102.

[0140] Specifically, in order to enable the pull-up stabilization module 103 to stabilize the auxiliary pull-up module 102, as the input voltage (i.e. V IN ) continues to increase, the first transistor Q1 and the second transistor Q2 start to conduct, at this time the negative feedback loop formed by the first transistor Q1, the second transistor Q2, the third P-type transistor MP3, the fourth P-type transistor MP4, the fifth P-type transistor MP5, the sixth P-type transistor MP6, the fourth N-type transistor MN4, the fifth N-type transistor MN5, and the seventh resistor R7 starts to work, for stabilizing the node voltage of the input node (i.e. the REGULATE node) of the auxiliary pull-up module 102, which can be the gate voltage of the sixth N-type transistor MN6, or the source voltage of the fourth P-type transistor MP4 to the sixth P-type transistor MP6, or the source voltage of the third current mirror formed by the fourth N-type transistor MN4 and the fifth N-type transistor MN5.

[0141] For the negative feedback loop, when the base voltage of the first transistor Q1 of the pull-up stabilization module 102 rises, the gate voltage of the third P-type transistor MP3 will drop, at this time the source voltage of the third P-type transistor MP3 will also drop, and the gate voltage of the fourth N-type transistor MN4 will drop accordingly. The source voltage of the fifth N-type transistor MN5 will follow the drop, and through the branch of the sixth P-type transistor MP6, it is transmitted to the base of the first transistor Q1, causing the base of the first transistor Q1 to drop, and thus the negative feedback is formed.

[0142] The negative feedback will break the positive feedback cycle of the auxiliary pull-up module 102 branch, and finally the base of the first transistor Q1 of the pull-up stabilization module 103 will be stabilized near the bandgap voltage, and the node voltage of the input node (REGULATE node) of the auxiliary pull-up module 102 will remain stable. The node voltage after stabilization can be equal to the sum of the bandgap voltage and the on voltage of the third P-type transistor MP3. Therefore, based on the above-mentioned FIG. 2 and FIG. 3 The driving circuit device shown in the figure can meet the condition that the output voltage (i.e. V IN ) of the starting circuit module 101 and the input voltage are almost without voltage difference under lower input voltage (i.e. V OUT ), thereby meeting the excellent effect of wider range of output voltage under lower input starting voltage.

[0143] It should be further pointed out that in the embodiment of the present application, the transistor mentioned can be a metal-oxide-semiconductor field-effect transistor (MOSFET for short). Among them, the N-type transistor can be an N-type doped MOSFET transistor, and the P-type transistor can be a P-type doped MOSFET transistor. Further, as FIG. 3 shown in the figure, the first N-type transistor MN1, the sixth N-type transistor MN6, the seventh P-type transistor MP7, and the eighth P-type transistor MP8 can all be high-voltage (HV for short) MOSFET devices, and correspondingly, other N-type transistors and P-type transistors are low-voltage (LV for short) MOSFET devices. The first transistor Q1 and the second transistor Q2 are ordinary low-voltage N-type transistors.

[0144] In summary, the driving circuit device of the embodiment of the present application is as FIG. 2 shown in the figure, the output control process of the driving waveform of the driving circuit device is mainly as follows:

[0145] Before the initial start-up phase T1 of the circuit, the start-up circuit module 101 is connected to the input electrical signal V. IN The input electrical signal V IN The voltage gradually increases. When the gate voltage of the first N-type transistor MN1 exceeds its threshold voltage, the first N-type transistor MN1 turns on, thereby gradually increasing the output electrical signal V at the output terminal. OUT The circuit enters its initial startup phase T1. During this phase, the output electrical signal V... OUT The input voltage can be connected to the input terminal of the pull-up stabilization module 103, so that the actual operating voltage of the pull-up stabilization module 103 gradually increases and meets its preset operating voltage. When the pull-up stabilization module 103 generates an enable electrical signal V to be output to the auxiliary pull-up module 102. G_MN6 Then, enter the pull-up trigger phase T2.

[0146] During the pull-up trigger phase T2, the input electrical signal V is at this time. IN and output electrical signal V OUT All remain stable at this time, and the input electrical signal V IN The voltage has stabilized at the sum of the threshold voltage of the first N-type transistor MN1 in the startup circuit module 101 and the threshold voltage of the second N-type transistor MN2 in the pull-up stabilization module 103. At this time, current begins to flow through the branch of the third resistor R3 in the pull-up stabilization module 103 and the first P-type transistor MP1. The current from the first P-type transistor MP1 is replicated to the branch of the second P-type transistor MP2 through the second current mirror formed by the first P-type transistor MP1 and the second P-type transistor MP2, causing the second P-type transistor MP2 branch to conduct. At this time, the pull-up stabilization module 103 controls the start-up electrical signal V. G_MN6 The gate of the sixth N-type transistor MN6 of the input auxiliary pull-up module 102 is increased, so that the gate voltage of the sixth N-type transistor MN6 is increased. When the gate voltage of the sixth N-type transistor MN6 meets the threshold voltage, the auxiliary pull-up action stage T3 is entered.

[0147] During the auxiliary pull-up phase T3, the turn-on signal V applied to the gate of the sixth N-type transistor MN6 is... G_MN6 The voltage has risen to a level greater than or equal to the on-state voltage (threshold voltage) of the sixth N-type transistor MN6, and current begins to flow through the ninth resistor R9 and the branch of the seventh P-type transistor MP7 in the auxiliary pull-up module 102. At this time, the current of the seventh P-type transistor MP7 is replicated by the first current mirror composed of the seventh P-type transistor MP7 and the eighth P-type transistor MP8, causing the current in the branch of the eighth P-type transistor MP8 to increase, outputting a pull-up signal to the startup circuit module 101, thereby assisting in pulling up the output signal V at the output terminal of the startup circuit module 101. OUT At this point, the auxiliary pull-up module 102 officially begins to work.

[0148] In this auxiliary pull-up phase T3, due to the rising of the output electrical signal V OUT , the gate voltage of the sixth N-type transistor MN6 continues to rise, the current of the ninth resistor R9 and the seventh P-type transistor MP7 branch continues to increase, so that the pull-up current I _MP8 (outputted by the eighth P-type transistor MP8, i.e. the pull-up electrical signal) further increases, and the output electrical signal V OUT continues to be pulled up. At the same time, due to the increase of the output electrical signal V OUT , the gate-source voltage difference (the voltage difference between the gate voltage and the source voltage) of the first N-type transistor MN1 decreases, and the current I _MN1 flowing through the first N-type transistor MN1 continues to decrease. When the current I _MP8 of the eighth P-type transistor MP8 exceeds a certain value of the current I _MN1 of the first N-type transistor MN1, the pull-up current I OUT of the output electrical signal V _MP8 is only provided by the current of the eighth P-type transistor MP8, and the entire driving circuit device will enter a stable phase and output the target driving electrical signal.

[0149] It should be noted that for the above-mentioned initial start-up phase T1, pull-up trigger phase T2 and auxiliary pull-up phase T3 of the embodiment of the present application, they only exist in the period T from when the first N-type transistor MN1 is turned on after the start-up circuit module 101 is connected to the input electrical signal V IN to the output of the target on electrical signal, i.e. T = T1+ T2+ T3. This period T is actually very short, which may be in the order of milliseconds or even smaller, and almost has no adverse effect on driving the load. Among them, the period from when the input electrical signal V IN is connected to when the first N-type transistor MN1 is turned on is even shorter and can be almost ignored. For this, those skilled in the art should understand that it will not be described in detail.

[0150] In the output control process of the driving waveform of the driving circuit device of the above-mentioned embodiment of the present application, the specific related technical principles are as follows:

[0151] As shown in FIG. 2 , when the input electrical signal V IN of the start-up circuit module 101 has a low value, the voltage of the first resistor R1 is large, at this time the current flowing through the first resistor R1 is small, so the voltage difference of the first resistor R1 is small, so that the gate voltage on the gate of the first N-type transistor MN1 is approximately equal to the voltage value of the input electrical signal V IN . At this time, when the input electrical signal V INhigher than the turn-on voltage of the first N-type transistor MN1, at this time the output electrical signal satisfies: V OUT = V IN -V GS1 .

[0152] When the input electrical signal V IN increases to the sum of the turn-on voltages of the first N-type transistor MN1 and the second N-type transistor MN2, at this time the second N-type transistor MN2 of the pull-up stabilization module 103 is turned on, the first P-type transistor MP1 of the pull-up stabilization module 103 has current, the branch of the first P-type transistor MP1 begins to generate current, and the current of the first P-type transistor MP1 is copied to the second P-type transistor MP2 through the second current mirror. At this time, the input electrical signal V IN voltage is low, about the turn-on voltage of two N-type MOS (NMOS), then the first transistor Q1 of the pull-up stabilization module 103 is not turned on, and the gate voltage of the third P-type transistor MP3 is pulled up by the fourth P-type transistor MP4, so that the third P-type transistor MP3 is in the off state. At this time, the gate voltage of the sixth N-type transistor MN6 is the source voltage of the third P-type transistor MP3, and the third P-type transistor MP3 pulls down the gate voltage of the sixth N-type transistor MN6, and the fourth N-type transistor MN4 pulls up the gate voltage of the sixth N-type transistor MN6. Therefore, when the third P-type transistor MP3 is in the off state, the source of the third P-type transistor MP3 will be always pulled up by the fourth N-type transistor MN4, so as to rise together with the output electrical signal V OUT of the output node of the starting circuit module 101.

[0153] Further, as shown in FIG. 2 , the auxiliary pull-up module 102 begins to work when the input electrical signal V IN continuously rises. Specifically, as the input electrical signal V IN voltage rises, the source voltage of the fourth N-type transistor MN4 of the pull-up stabilization module 103 will rise together with the output electrical signal V OUT , and when the source voltage of the fourth N-type transistor MN4 rises to turn on the sixth N-type transistor MN6 of the auxiliary pull-up module 102, at this time the auxiliary pull-up module 102 is turned on and begins to work. The sixth N-type transistor MN6 and the ninth resistor R9 in series with it generate a source current, which is copied to the eighth P-type transistor MP8 through the seventh P-type transistor MP7 of the first current mirror, so that the eighth P-type transistor MP8 outputs a pull-up electrical signal to pull up the output electrical signal V OUT of the output node of the starting circuit module 101. The output node voltage V OUTThe voltage increase causes the source voltage of the fourth N-type transistor MN4 in the pull-up stabilization module 103 to further increase, which in turn affects the gate of the sixth N-type transistor MN6 in the auxiliary pull-up module 102. The current in the branch of the sixth N-type transistor MN6 increases accordingly, replicating the current again to the eighth P-type transistor MP8, thus strengthening the pull-up effect on the startup circuit module 101, thereby forming positive feedback. Therefore, when the output electrical signal V... OUT Pulled up by the eighth P-type transistor MP8 to near the input electrical signal V IN When the amplitude is reached, the first N-type transistor MN1 is cut off, the startup circuit module 101 is turned off, the auxiliary pull-up module 102 provides pull-up current, and the output electrical signal V is generated. OUT Ultimately, stability is achieved when the target signal is activated.

[0154] As for the pull-up stabilization module 103, its... FIG. 1C The diagram shows a bandgap reference circuit structure, primarily used to stabilize the auxiliary pull-up module 102. As the input voltage (i.e., V...) increases... IN As the current continues to increase, the first transistor Q1 and the second transistor Q2 begin to conduct. At this time, the negative feedback loop formed by the first transistor Q1, the second transistor Q2, the third P-type transistor MP3, the fourth P-type transistor MP4, the fifth P-type transistor MP5, the sixth P-type transistor MP6, the fourth N-type transistor MN4, the fifth N-type transistor MN5, and the seventh resistor R7 begins to work. This loop is used to stabilize the node voltage of the input node (i.e., the REGULATE node) of the auxiliary pull-up module 102. This node voltage can be the gate voltage of the sixth N-type transistor MN6, or the source voltage of the fourth P-type transistor MP4 to the sixth P-type transistor MP6, or the source voltage of the third current mirror formed by the fourth N-type transistor MN4 and the fifth N-type transistor MN5.

[0155] In this negative feedback loop, when the base voltage of the first transistor Q1 in the pull-up stabilization module 102 increases, the gate voltage of the third P-type transistor MP3 decreases. At this time, the source voltage of the third P-type transistor MP3 also decreases, and the corresponding gate voltage of the fourth N-type transistor MN4 decreases. The source voltage of the fifth N-type transistor MN5 also decreases, and the voltage is transmitted to the base of the first transistor Q1 through the branch of the sixth P-type transistor MP6, causing the base voltage of the first transistor Q1 to decrease. Thus, the negative feedback is formed.

[0156] Specifically, this negative feedback breaks the positive feedback loop of the previous auxiliary pull-up module 102 branch, ultimately stabilizing the base of the first transistor Q1 in the pull-up stabilization module 103 near the bandgap voltage. The node voltage of the input node (REGULATE node) of the auxiliary pull-up module 102 remains stable; specifically, this stabilized node voltage can be equal to the sum of the bandgap voltage and the on-state voltage of the third P-type transistor MP3. Therefore, based on the above embodiments of the present invention... FIG. 2 and FIG. 4 The drive circuit shown can meet the requirements at a lower input voltage (i.e., V). IN In the case of ), the output voltage (i.e., V) of the starting circuit module 101 OUT There is almost no voltage difference between the input voltage and the output voltage, thus achieving the excellent effect of a wider range of output voltages while maintaining a lower input start-up voltage.

[0157] Therefore, as FIGS. 4-6 As shown, the driving circuit device described above in this embodiment of the invention can realize the input electrical signal V during the load driving process. IN With output electrical signal V OUT With a smaller pressure difference (dropout) between them, at least the following technical effects can be achieved:

[0158] (1) It can provide a wide-range startup circuit. By adding an auxiliary pull-up module as an auxiliary branch, it can be used for normal operation under lower input voltage conditions, which can meet the power supply requirements of a wide input power supply voltage range, meet different voltage requirements, improve system flexibility, and adapt to more different scenarios. At the same time, lower input voltage conditions can improve battery utilization, reduce dependence on external power supply, and reduce system cost.

[0159] (2) The wide-range startup circuit has a wide operating environment. It has been verified by PVT (Process Voltage Temperature) that it can work stably under high and low voltage, high and low temperature and various process angles, and has better stability.

[0160] Therefore, compared to traditional technologies that cannot effectively balance small input voltages and large output voltages, the driving circuit device described in this embodiment of the invention, with the aid pull-up module 102, can assist in boosting the output voltage of the startup circuit module 101 under a small input voltage, thereby achieving a wider range of voltage output from the startup circuit module 101, through the output electrical signal V. OUT and input electrical signal V INThe smaller pressure difference between the two, the lower power consumption, while you can further reduce the minimum input voltage required by the chip to effectively avoid the system error when the battery power is about to run out, improve the system stability, reduce the dependence on external power supply, reduce the system cost, improve the battery utilization, can meet the voltage demand in different ranges, improve flexibility, wider application range, higher economic practical value.
