[0002] The automotive lighting industry has entered a period of vigorous development, with the main trend being the rapid development towards LED (light-emitting diode).

[0003] At present, the reverse light and the turn signal share the same driver chip; when the reverse light fails, that is, when the reverse light cannot be turned on, the driver chip is in an error state and cannot respond to the control signal normally. If the turn signal needs to be enabled at this time, the driver chip cannot respond to the control signal of the turn signal normally, resulting in the turn signal that is not faulty not being turned on, which in turn causes the turn signal that is not faulty to be falsely reported as faulty.

[0004] Therefore, how to reduce the possibility of the turn signal being falsely reported as malfunctioning when the turn signal is not malfunctioning is a technical problem that needs to be solved urgently. Utility Model Content

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] In a first aspect, the present application provides a fault reset circuit for a driver chip, comprising: a switch tube, a first capacitor branch, a second capacitor branch, and a first resistor branch connected in parallel with the second capacitor branch; wherein:

[0008] One end of the first capacitor branch serves as an input end of the fault reset circuit, and is used to receive an enable signal of a controlled component; the controlled component is a component controlled by the driving chip;

[0025] Optionally, the controlled component is a vehicle light.

[0026] Optionally, the switch tube includes: a MOS tube, an IGBT or a triode.

[0027] The second aspect of the present application provides a vehicle light control circuit, comprising: a driver chip and at least one fault reset circuit of the driver chip as described in any one of the first aspects of the present application; wherein:

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0038] In order to reduce the possibility of the turn signal being falsely reported as a fault when the turn signal is not faulty, the embodiment of the present application provides a fault reset circuit of a driver chip, and its specific structure is as follows: Figure 1 As shown, it specifically includes: a switch tube Q, a first capacitor branch 10, a second capacitor branch 20 and a first resistor branch 30; the connection relationship between the components is specifically as follows:

[0039] One end of the first capacitor branch 10 serves as an input end of the fault reset circuit, and is used to receive an enable signal RT of the controlled component.

[0040] The controlled component is a component controlled by the driver chip 01 .

[0041] When the enable signal RT of the controlled component is at a high level, the driver chip 01 responds to the control signal of the controlled component; when the enable signal RT of the controlled component is at a low level, the driver chip 01 does not respond to the control signal of the controlled component.

[0042] Optionally, the controlled component may be a vehicle lamp, that is, a lamp on a vehicle, such as a reversing light, etc. In practical applications, this includes but is not limited to this, and is not specifically limited here. It may depend on the specific circumstances and is within the scope of protection of this application.

[0043] Optionally, the vehicle lights may be turn signals or reverse lights. In practical applications, these may include but are not limited to these. No specific limitation is made here and the specific circumstances may determine, all of which are within the scope of protection of this application.

[0044] For example, when the enable signal of the turn signal is at a high level, the driver chip responds to the control signal of the turn signal. For another example, when the enable signal of the reversing light is at a high level, the driver chip responds to the control signal of the reversing light.

[0045] It should be noted that the high level and the low level of the enable signal RT are determined according to actual conditions. As for how to determine it, it is already very mature in the prior art and will not be described in detail here.

[0046] In addition, the first capacitor branch 10 includes at least one capacitor; if the number of capacitors is greater than 1, all capacitors are connected in series and in parallel, and the two ends of the formed connection branch serve as the two ends of the first capacitor branch 10; if the number of capacitors is equal to 1, the two ends of the capacitor serve as the two ends of the first capacitor branch 10, for example, Figure 1 As shown in C1.

[0047] The other end of the first capacitor branch 10 is connected to one end of the second capacitor branch 20 , and the other end of the second capacitor branch 20 is grounded GND.

[0048] The second capacitor branch 20 includes at least one capacitor; if the number of capacitors is greater than 1, all capacitors are connected in series and in parallel, and the two ends of the formed connection branch serve as the two ends of the second capacitor branch 20; if the number of capacitors is equal to 1, the two ends of the capacitor serve as the two ends of the second capacitor branch 20, for example, Figure 1 As shown in C2.

[0049] The connection point between the first capacitor branch 10 and the second capacitor branch 20 is connected to: the control end of the switch tube Q, the input end of the switch tube Q receives the power supply voltage VCC, and the output end of the switch tube Q is grounded GND.

[0050] Among them, the switch tube Q is an NPN type tube, that is, the switch tube Q is turned on when its own control end is at a high level, and is turned off when its own control end is at a low level.

[0051] It should be noted that the high level and low level of the control end of the switch tube Q are determined according to the specific type and model of the switch tube Q. As for how to determine it, it is already very mature in the prior art and will not be described in detail here.

[0052] Optionally, the switch tube Q can be a MOS tube, an IGBT, or a triode. In practical applications, this includes but is not limited to these. No specific limitation is made here and it can be determined according to the specific circumstances. All of them are within the protection scope of this application.

[0053] The input end of the switch tube Q serves as the output end of the fault reset circuit and is connected to the enable end EN of the driver chip 01 .

[0054] The first resistance branch 30 is connected in parallel with the second capacitance branch 20 .

[0055] The first resistance branch 30 includes at least one resistor; if the number of resistors is greater than 1, all resistors are connected in parallel, and the two ends of the formed connection branch serve as the two ends of the first resistance branch 30; if the number of resistors is equal to 1, the two ends of the resistor serve as the two ends of the first resistance branch 30, for example, Figure 1 As shown in R1.

[0056] The working principle is as follows:

[0057] When the enable signal RT is at a high level, one end of the series branch formed by the first capacitor branch 10 and the second capacitor branch 20 is at a high level and the other end is at a ground level, so that the first capacitor branch 10 and the second capacitor branch 20 are charged.

[0058] During the charging process of the first capacitor branch 10 and the second capacitor branch 20, the voltage across the first capacitor branch 20 increases continuously; when the second capacitor branch 20 is charged to a certain level, the potential at the connection point between the first capacitor branch 10 and the second capacitor branch 20 reaches a high level, thereby turning on the switch tube Q, and then lowering the potential of the input end of the switch tube Q, that is, lowering the potential of the enable end EN of the driver chip 01, thereby resetting the driver chip 01.

[0059] When the first capacitor branch 10 and the second capacitor branch 20 are fully charged, since the first capacitor branch 10 is equivalent to an open circuit, the energy on the second capacitor branch 20 will be released through the first resistor branch; when released to a certain extent, the potential at the connection point between the first capacitor branch 10 and the second capacitor branch 20 becomes a low level, thereby turning off the switch tube Q, and then raising the potential of the input end of the switch tube Q, that is, raising the potential of the enable end EN of the driver chip 01, thereby enabling the driver chip 01.

[0060] When the enable signal RT is at a low level, one end of the series branch formed by the first capacitor branch 10 and the second capacitor branch 20 is at a low level and the other end is at a ground level. Since the low level of the enable signal RT is generally approximately equal to the ground level, the first capacitor branch 10 and the second capacitor branch 20 stop charging.

[0061] From the above, it can be seen that the driver chip 01 is first reset and then enabled, that is, the driver chip is restarted, so the error state of the driver chip is cleared, that is, the driver chip can normally respond to the control signal of the controlled component, thereby reducing the possibility of the controlled component being falsely reported as a fault when the controlled component is not faulty; since the controlled component can be a turn signal, the fault reset circuit can reduce the possibility of the turn signal being falsely reported as a fault when the turn signal is not faulty.

[0062] Another embodiment of the present application provides another implementation of a fault reset circuit of a driver chip, and its specific structure is as follows: Figure 2 As shown, this embodiment, based on the above embodiment, further includes: a second resistor branch 40 and a third resistor branch 50; the connection relationship between the components is specifically described as follows:

[0063] The second resistance branch 40 and the third resistance branch 50 are connected in series, one end of the series branch receives the enable signal RT of the controlled component, and the other end of the series branch is grounded GND.

[0064] The second resistance branch 40 includes at least one resistor; if the number of resistors is greater than 1, all resistors are connected in parallel, and the two ends of the formed connection branch serve as the two ends of the second resistance branch 40; if the number of resistors is equal to 1, the two ends of the resistor serve as the two ends of the second resistance branch 40, for example, Figure 2 As shown in R2.

[0065] The third resistance branch 50 includes at least one resistor; if the number of resistors is greater than 1, all resistors are connected in parallel, and the two ends of the formed connection branch serve as the two ends of the third resistance branch 50; if the number of resistors is equal to 1, the two ends of the resistor serve as the two ends of the third resistance branch 50, for example, Figure 2 As shown in R3.

[0066] The connection point between the second resistance branch 40 and the third resistance branch 50 is connected to: an end of the first capacitance branch 10 that is not connected to the second capacitance branch 20 .

[0067] In this embodiment, the second resistor branch 40 and the third resistor branch 50 are used to divide the high level of the enable signal RT, thereby reducing the possibility of damage to the first capacitor branch 10, the second capacitor branch 20 and the switch tube Q, thereby improving the safety of the fault reset circuit.

[0068] Another embodiment of the present application provides another implementation of the fault reset circuit of the driver chip, and its specific structure can be found in Figure 3 ( Figure 3 Only in Figure 2 Based on the above embodiment, this embodiment further includes: a clamping branch 60; the connection relationship between the components is as follows:

[0069] The clamping branch 60 is connected in parallel with the second capacitor branch 20 , wherein the clamping circuit 60 is used to clamp the voltage across the second capacitor branch 20 to a preset voltage when the voltage across the second capacitor branch 20 exceeds a preset threshold voltage.

[0070] It should be noted that the preset threshold voltage and the preset voltage are both determined according to the actual situation of the clamping circuit 60, and are not specifically limited here. As for how to determine them, the prior art is already very mature and will not be repeated here.

[0071] In a specific example, if Figure 4 ( Figure 4 Only in Figure 3 As shown in the figure, the clamping branch 60 includes a TVS (Transient Voltage Suppressor) branch 61, the cathode of the TVS branch 61 is connected to: the connection point of the first capacitor branch 10 and the second capacitor branch 20, and the anode of the TVS branch 61 is connected to: an end of the second capacitor branch 20 that is not connected to the first capacitor branch 10.

[0072] Among them, the TVS branch 61 includes at least one TVS; if the number of TVS is greater than 1, all TVSs are connected in series in the same direction, and the anode of the series branch formed is used as the anode of the TVS branch 61, and the cathode of the series branch formed is used as the cathode of the TVS branch 61; if the number of TVS is equal to 1, the anode of the TVS is used as the anode of the TVS branch 61, and the cathode of the TVS is used as the cathode of the TVS branch 61, for example, Figure 4 As shown in the TV.

[0073] In another specific example, Figure 5 ( Figure 5 Only in Figure 3 As shown in the figure, the clamping branch 60 includes a zener diode branch 62, the cathode of the zener diode branch 62 is connected to: the connection point of the first capacitor branch and the second capacitor branch, and the anode of the zener diode branch 62 is connected to: an end of the second capacitor branch that is not connected to the first capacitor branch.

[0074] Wherein, the voltage-stabilizing diode branch 62 includes at least one voltage-stabilizing diode; if the number of voltage-stabilizing diodes is greater than 1, all the voltage-stabilizing diodes are connected in series in the same direction, and the anode of the series branch formed is used as the anode of the voltage-stabilizing diode branch 62, and the cathode of the series branch formed is used as the cathode of the voltage-stabilizing diode branch 62; if the number of voltage-stabilizing diodes is equal to 1, the anode of the voltage-stabilizing diode is used as the anode of the voltage-stabilizing diode branch 62, and the cathode of the voltage-stabilizing diode is used as the cathode of the voltage-stabilizing diode branch 62, for example, Figure 5 As shown in Z.

[0075] The above two examples only show two implementation methods of the clamping branch 60. In practical applications, including but not limited to these, no specific limitation is made here and it can be determined according to the specific situation, all of which are within the protection scope of this application.

[0076] In this embodiment, the voltage across the second capacitor branch 20 can be clamped by the clamping circuit 60, thereby reducing the possibility of damage to the second capacitor branch 20 and the switch tube Q, thereby improving the safety of the fault reset circuit.

[0077] Another embodiment of the present application provides another implementation of the fault reset circuit of the driver chip, and its specific structure can be found in Figure 6 ( Figure 6 Only in Figure 4 Based on the above embodiment, this embodiment further includes: a fourth resistor branch 70; the connection relationship between the components is as follows:

[0078] One end of the fourth resistance branch 70 is connected to the input end of the switch tube Q, and the other end of the fourth resistance branch 70 receives the power supply voltage VCC.

[0079] The fourth resistor branch 70 includes at least one resistor; if the number of resistors is greater than 1, all resistors are connected in parallel, and the two ends of the formed connection branch serve as the two ends of the fourth resistor branch 70; if the number of resistors is equal to 1, the two ends of the resistor serve as the two ends of the fourth resistor branch 70, for example, Figure 6 As shown in R4.

[0080] In this implementation, the fourth resistance branch is used to reduce the current at the output end of the fault reset circuit, thereby reducing the possibility of damaging the driver chip 01 and further improving the safety of the fault reset circuit.

[0081] Another embodiment of the present application provides a vehicle light control circuit, and its specific structure can be seen in Figure 7 ( Figure 7 Only in Figure 6 or Figure 8 ( Figure 8 Only in Figure 6 ), specifically comprising: a driver chip 01 and at least one fault reset circuit 02 of the driver chip provided in the above embodiment.

[0083] For example, Figure 7 As shown, the enable end of the driver chip 01 receives the enable signal RT1 of the reversing light, and the enable end of the driver chip 01 also receives the enable signal RT2 of the turn light through a fault reset circuit 02. The enable end of the driver chip 01 also receives the enable signal RT3 of other lights controlled by the driver chip 01 through a fault reset circuit 02.
