Field of the Invention This invention relates to an electrostatic protection circuit device, and more particularly to a device for electrostatically protecting two different supply voltages using a transistor element. [Prior Art] Please refer to Fig. 1, which is a schematic Φ diagram of a conventional electrostatic protection circuit 10. The electrostatic protection circuit 10 includes a first set of diodes 11 connected in series and a second set of diodes 12 connected in series. The first series of diodes η are coupled to a first power terminal N1 and a second power terminal N2, wherein the first power terminal 111 is configured to receive a first voltage source Vddl and a first power source. Terminal N2 is for receiving a second voltage source Vdd2. Similarly, the second series of diodes 12 are also coupled to the first power terminal m and the first power terminal N2, and the difference is that the first voltage source vddl is opposite to the first voltage source Vdd2'. In the normal operation, Vdd2 > Vddl is taken as an example. The first group of φ-connected diodes 11 are forward, and the second group of connected diodes 12 are reversed. When one of the first power supply terminal N1 and the first power supply terminal N2 has an electrostatic pulse signal, the first power supply terminal N1 is taken as an example, and the second series of diodes 12 are turned on and according to the electrostatic pulse signal. The amplitude synchronously increases the voltages of the first power terminal N1 and the first power terminal N2, respectively. Conversely, when the second power terminal N2 has an electrostatic pulse signal, the first series of diodes u are turned on and the first power terminal N1 and the second power terminal N2 are synchronously boosted according to the amplitude of the electrostatic pulse signal. The voltage of * respectively. In this way, the circuit system corresponding to the first voltage source Vddl and the second voltage source Vdd2 does not generate a huge voltage difference and causes damage to components in the circuit system. However, the conventional electrostatic protection circuit 10 has at least two problems. First, when the voltage difference between the first voltage source Vddl and the second voltage source Vdd2 required by the system is too large, the first group is connected in series. The number of poles of the pole body 11 and the second group of diodes 12 connected in series must be appropriately increased, but when the number of diodes is too large, the reaction of the electrostatic protection circuit 1〇 is too slow to be performed. The voltages of the first power terminal N1 and the second power terminal n2 are synchronously synchronized in time. Second, in the implementation of the voltage source Vddll potential & pi ^ m pressure source Vddl invites the flute "mouth this Tiandi an electric ^ first - the voltage source Vdd2 is not synchronously turned on or off will be in the first: current:: body U or the second set of serially connected diodes 12 produces a large amount of directional damage. The cis-conducting current is extremely easy to cause damage to the components in the circuit system. [Inventive content] The embodiment provides a circuit device, including: a first switch element, a control unit, a second switch element, and a second control element. The sweat element has a "first end" coupled to - a first signal to which the first control signal is generated according to the second signal element; the second control element has a first The second end of the signal is coupled to the second end of the first switching element; 1332736 and the second control element are coupled to the second signal and the first switching element to control Based on the second signal to generate a second control signal; wherein the first control The wire is connected to the second remaining control end, and the second control signal is coupled to the control end of the first switch. [Embodiment] Certain words are used in the specification and subsequent application. To refer to • specific components. Those with ordinary knowledge in the field should understand that hardware manufacturers may use different names to refer to the same component. The scope of this specification and subsequent patent applications are not by name. As a way of distinguishing between components, but using the difference in function of the components as the distinction between the Ml, the "contains" mentioned in the book and the subsequent claims are open-type, so It is "including but not limited to". In addition, the term "lightweight" is used in this context to include any direct and indirect electrical connection means. If the description - the device touches a second installation, it means that the first device can be directly electrically connected. In the second light, or indirectly connected to the second device through other devices or connecting means. FIG. 2 is a schematic view of an embodiment of an electrostatic protection circuit device 200 according to the present invention. The electrostatic protection circuit device includes a first switching element plus a -th-control element 2〇2 a second switching element 2〇3 and a first control element. The embodiment of the present invention provides a static protection mechanism between the -th supply voltage terminal Ny〇D1 and the second supply voltage terminal ,·!, wherein the first-supply voltage terminal Nv〇 d> second electric 9 1332736 • source voltage terminal Ν · 2 minutes to accept - the first power supply Vdd] and - second power voltage terminal vDD2, and the first supply voltage vDD1 is not equal to the second electric her, vDm . Therefore, when the electrostatic protection circuit device 2 (10) of the present invention operates in the two normal mode, the first end of the first switching element 201 (that is, the first power supply system is used to receive the first power supply voltage vDD1; the first control element 2〇2 is input to the fifth source voltage terminal NvdD1 and one of the second switching elements 203, the control terminal N.2, for generating a -first control signal according to the first power supply voltage vDD丨; and the second switching element 2〇2 #有—第第端 (that is, the first-supply voltage terminal NvdD2) the wire receives the second power voltage terminal VDm, and the second terminal Nbulk is coupled to the second terminal of the first switching element 2〇1 (ie, Nbulk And the second control component 204 is coupled to the second power supply voltage terminal Vdd2 and the control terminal Ncl of the first switching component 201 for generating a second control signal v. 2 according to the second power voltage terminal Vdd2; The first control signal Vci is coupled to the control terminal N. 2 of the first control element 202, and the second control signal ν. 2 is coupled to the control terminal Ncl of the second control element 204. On the other hand, for a clearer description The essence of the present invention is the first in the electrostatic protection circuit device 200 of the present embodiment. The closing element 2〇1 is a first P-type field effect transistor MP1, and the control terminal Ncl of the first switching element 201 is one of the gates of the first p-type field effect transistor; the second switching element 2〇3 It is a second P-type field effect transistor Mm, and the control terminal nc2 of the second switching element 203 is a gate of the second P-type field effect transistor Μη. Please note that those skilled in the art should be able to understand By appropriately adjusting the electrostatic protection circuit device 2 of the embodiment of the present invention, the first switching element 201 and the second switching element 203 can also be implemented by two N-type field effect transistors. On the other hand, the first The control component 202 is a first filter, which is composed of a capacitor C1 and a resistor R1 for generating a first control signal Vci for the first power voltage vDD1 1332736 * . * * *; The second control component 204 is a second filter composed of a capacitor C2 and a resistor R2 for filtering the second power voltage VDm to generate a second control signal 乂. 2. Please note that the A ferrite and the second filter are both low pass filter circuits, and the first p-field Substrate of one of the transistors MP1 is coupled to the second known Nbulk of the first P-type field effect transistor ,, and one of the second p-type field effect transistors Mm is lightly connected to the second p-type field effect The second end of the transistor Μη (also known as Nbulk) 'the first one] p-type field effect transistor Μρι • the substrate and the second P-type field effect transistor MP2 of the substrate are in a floating state, As shown in Fig. 2, an electrostatic protection circuit device 2 according to an embodiment of the present invention can be divided into a DC supply mode and an ESD protection mode. Please refer to FIG. 3, which is a schematic diagram of the electrostatic protection circuit device 2 of the embodiment of the present invention operating in the DC supply mode. In order to more clearly describe the spirit of the present invention, the first power supply voltage Vddi is set higher than the second power supply voltage VDD2, for example, VDD1 = l 〇 V, Vdd2 = 5 volts. Therefore, when vDD1=iov, the control terminal Nc2 of the second P-type field effect transistor Mp2 will also charge to 10V (ie, the first control signal Vcl)e. On the other hand, when Vdd2=5v, the P-type field The control terminal Ncl of the utility device will also charge to 5V (ie, the second control signal V. 2). Therefore, the first p-type field effect transistor Μρι will be turned on to generate a conduction current 1_-〇η1. The second end of the first P-type field effect transistor MP1 is charged 'up until the voltage of the Hth reaches 10V. As a result, * the second p-type field effect transistor Mp2 will be turned off. It can be seen that when the electrostatic protection circuit device 200 of the embodiment of the present invention operates in the DC supply mode, the first power source voltage VDD1 is not conducted to the second power source voltage Vdd2. Conversely, when the first power supply voltage VDD1 is set lower than the second power supply voltage vDD2, for example, V(10)=5V, > the second P-type field effect transistor Mp2 is turned on and the first-p-type field effect transistor MP1 side is turned on. _. Shame in the DC supply mode, the first power supply voltage V (10) and the second power supply voltage % can positively provide the electric DD DD1 to the corresponding circuit. 5 Green reference FIG. 4 is shown in FIG. The electrostatic protection circuit device 200 of the embodiment is operated in the manner of (4) in order to more clearly describe the spirit of the present invention. In the initial state, the electrostatic protection circuit device 2 is operating in the DC supply mode. For example, the first power supply %% is 1〇v and the second power supply voltage VDD2 is 5V. When the first power supply voltage of the first power supply voltage terminal Nvddi has an electrostatic (ESD)_, the electrostatic pulse immediately raises the first power supply voltage vDD1 far beyond the normal 10V', for example, when the electrostatic pulse is a ι〇ν During the transient pulse, the 'first-supply voltage terminal'-supply voltage % is boosted from J_20V as shown in Figure 4. Since the first p-type field effect transistor MP1 is in an on state in the initial state, the first-p(tetra) effect transistor generates a conduction current ι-η2 to flow to the first p-type field effect transistor Μρι end. Please note that since the second end has been charged until the flow is supplied, the on current W instantaneously turns on the second p-type field effect transistor Mp2. Note that at the same time, the first chopper will cause the control terminal of the second p-type field effect transistor. 2 is temporarily at ι〇ν (first control signal Vci)e. Therefore, the second p-type field effect transistor Mp2 is turned on and flows the on current It〇_ to the second power source 12

Thus -T, the second power supply VDD2 of the N-side of the second power supply voltage terminal is upgraded from the original 5V to the Zhejiang. Please note that when the static pulse is turned on to the second power supply, the control terminal Nel of the P-type field effect transistor MP1 is temporarily maintained at 5v (second control signal vC2) to make the second The p-type field effect transistor Mp2 is continuously turned on until the end of the electrostatic pulse is h, so that it can be known that the electrostatic protection circuit device of the present invention operates in the electrostatic protection mode, the __ power supply voltage Vddi and the - The power supply voltage VDD2 synchronously raises the corresponding voltage level with the pulse amplitude of the electrostatic pulse, so that the circuit corresponding to the first power supply and the second power supply voltage VD〇2 can avoid electrostatic interference. It works normally. Conversely, when the second power supply voltage Vdd2 of the second power supply voltage terminal has an electrostatic (ESD) pulse, the skilled person will understand the embodiment of the present invention after reading the implementation operations disclosed above. The operation flow is presented, so it will not be described again. On the other hand, since the electrostatic protection circuit device 2 (8) of the embodiment of the present invention operates in the DC supply mode, one of the P-type field effect transistors must be in a closed state. Therefore, the first power supply voltage VDD1 and the second When the power supply voltage VDD2 is not synchronously turned off, a large forward current generated between the first power supply voltage VDD1 and the second power supply voltage VDD2 cannot be turned on between the first power supply voltage 4 NVDD1 and the second power supply voltage terminal Nvdd2. As a result, the circuit corresponding to the first power supply voltage 〇〇1 and the second power supply voltage Vdd2 is not damaged by the large forward current.
