[0059] Glossary

[0060] PMIC: Power Management Integrated Circuit

[0061] PCB: Printed Circuit Board

[0062] There are many types of vehicle-mounted camera products now, but the power chip circuits have poor compatibility. Power chip circuits need to be developed separately for different types of vehicle-mounted cameras, which prolongs the R&D cycle and cost and is not conducive to hardware management.

[0063] In view of the above problems, a camera module PMIC with high compatibility and a power supply method thereof are proposed.

[0064] First, a camera module PMIC with high compatibility, such as Figure 2 , Figure 2 It is a circuit structure diagram of the camera module in this application; it includes a power chip module, a voltage regulating module 100, and a timing control module 200; the voltage regulating module 100 is electrically connected to the power chip module, and is used to adjust the output voltage of each output channel according to the camera type; the timing control module 200 is electrically connected to the power chip module, and is used to control the output timing of each output channel according to the camera type. By setting the voltage regulating module 100, the voltage size of each output channel can be adjusted according to the camera model, and by setting the timing control module 200, the timing of the output channel can be adjusted according to the camera model, so as to meet the power supply voltage and timing performance requirements of various models of cameras, improve the compatibility of the power supply circuit, shorten the R&D cycle, and reduce the R&D cost.

[0065] In this embodiment, if Figure 1 , Figure 1 This is a schematic diagram of the circuit structure of the camera module; the basic design of the camera consists of PCB board 1 and PCB board 2. PCB board 1 is the image sensor circuit board, PCB board 2 is the PMIC power module circuit board, and PCB board 1 and PCB board 2 are connected by a connector. The PCB board stacking structure is not limited to two boards, but can also be two or more.

[0066] Specifically, Figure 3 The power chip module includes a processing chip U1 and a plurality of output channels; the plurality of output channels are respectively led out from pins of the processing chip U1.

[0067] In this embodiment, if Figure 3 , four output channels can be used, namely VCH1, VCH2, VCH3, and VCH4, which are connected to the above-mentioned processing chip U1 through their respective pins SW1, SW2, SW3, and SW4.

[0068] Specifically, the voltage regulating module 100 includes a plurality of voltage regulating units; the plurality of voltage regulating units are electrically connected to the plurality of output channels one by one, respectively, and are used to adjust the magnitude of the output voltage of each channel by adjusting the resistance.

[0069] Preferably, the number of output channels and voltage regulating units is 4; the output channels include a first output channel VCH1, a second output channel VCH2, a third output channel VCH3 and a fourth output channel VCH4; the voltage regulating units include a first voltage regulating unit, a second voltage regulating unit, a third voltage regulating unit and a fourth voltage regulating unit; the first voltage regulating unit, the second voltage regulating unit, the third voltage regulating unit and the fourth voltage regulating unit are electrically connected to the first output channel VCH1, the second output channel VCH2, the third output channel VCH3 and the fourth output channel VCH4 respectively; the first output channel VCH1 is used to provide power to the second output channel VCH2, the third output channel VCH3 and the fourth output channel VCH4 through the input pin with the power supply voltage converted by the processing chip; the second output channel VCH2, the third output channel VCH3 and the fourth output channel VCH4 are used to provide power supply voltage to the camera module.

[0070] like Figure 3 , Figure 3 It is a structural diagram of the electronic components connection between the power chip module and the voltage regulation module 100 in the present application; the first voltage regulation unit is electrically connected to the first output channel VCH1, includes resistors (R10, R11), and is also connected to the feedback pin FB1 of the processing chip U1; the second voltage regulation unit is electrically connected to the second output channel VCH2, includes resistors (R20, R21), and is also connected to the feedback pin FB2 of the processing chip U1; the third voltage regulation unit is electrically connected to the third output channel VCH3, includes resistors (R30, R31), and is also connected to the feedback pin FB3 of the processing chip U1; the fourth voltage regulation unit is electrically connected to the fourth output channel VCH4, includes resistors (R40, R41), and is also connected to the feedback pin FB4 of the processing chip U1.

[0071] In this embodiment, the PMIC power processing chip U1 outputs three power supply voltages to power the image sensor of the image sensor circuit board, and the output channels of the three power supplies are VCH2, VCH3, and VCH4 respectively. The voltages of the three power supplies output by the PMIC processing chip U1 can be set according to the requirements of the image sensor. If VCH2 needs to output 3.3V, only the resistance values ​​of R20 and R21 need to be changed. Similarly, by changing the resistance values ​​of R30 / R31 and R40 / R41, the output voltage values ​​of VCH3 and VCH4 can be set.

[0072] Specifically, the timing control module 200 includes multiple enable control input terminals, a timing adjustment unit, and multiple enable control output terminals; the timing adjustment unit sequentially inputs each enable control signal from the processing chip through the multiple enable control input terminals; the timing adjustment unit adjusts the output timing of the enable control signal according to the camera type, and outputs it to the processing chip U1 through the multiple enable control output terminals.

[0073] Preferably, the number of enable control input terminals is 4, which are used to input 4 enable control signals respectively; the number of enable control output terminals is 3, which are used to output enable control signals with specific timing to control the output of the second output channel, the third output channel and the fourth output channel.

[0074] In actual applications, image sensors of different types of camera modules have different requirements for power-on timing. Therefore, by changing the power-on sequence of the input enable terminals EN2, EN3, and EN4 of the three power supplies VCH2, VCH3, and VCH4 of the PMIC chip, different output sequences corresponding to the three power supplies can be output. For example, if the PMIC is set to output the power timing of VCH4-VCH3-VCH2, the enable output timing of the corresponding output channel is EN4-EN3-EN2.

[0075] like Figure 3 and Figure 4 , the enable control input terminals include PG1, PG2, PG3, PG4, and the enable output terminals include EN2, EN3, EN4.

[0076] Figure 3 The enable terminal EN1 in the embodiment is used to enable the input power supply. The voltage output by the first output channel VCH1 supplies power to the second output channel VCH2, the third output channel VCH3 and the fourth output channel VCH4 through the pin VIN234.

[0077] Specifically, the timing adjustment unit is a timing adjustment array, including 4 input rows and 3 output columns; wherein the first input row is a common row, electrically connected to all output columns, and any remaining input row is electrically connected to any two of the 3 output columns.

[0078] In this embodiment, the connection between the input row and the output column is connected through a resistor. The specific structure diagram is as follows: Figure 4 , including resistors (R1-R9).

[0079] Further, such as Figure 4 , Figure 4 It is a connection structure diagram of the electronic components of the timing control module 200 in the present application; the timing adjustment unit disconnects / connects the output column with the remaining input rows according to the camera type to adjust the timing of the enable control signal to obtain the enable output timing.

[0080] The PMIC design principle of the embodiment of the present application is:

[0081] After the PMIC chip U1 power supply input terminal VIN1 (pin13) inputs a DC 12V voltage, and the first output channel VCH1 power input enable terminal EN1 (pin12) is connected to the input power supply, so that EN1 is in a high-level enable state, the PMIC chip U1 outputs the first output channel VCH power supply VCH1 (pin15). The voltage value of the VCH1 output can be set according to the resistance values ​​of resistors R10 and R11. And the PMIC chip U1 first output channel VCH power supply output indication PG1 (pin9) outputs a high-level state, and the high-level state of PG1 indicates that the voltage output state of the first output channel VCH power supply VCH1 is normal.

[0082] After the voltage output of the first output channel VCH1 of the PMIC chip U1 is normal, power is supplied to the power input terminal VIN234 (pin10) of the second output channel VCH2, the third output channel VCH3, and the fourth output channel VCH4 of the chip U1.

[0083] When the second output channel VCH2, the third output channel VCH3, and the fourth output channel VCH4 power input enable terminals EN2 (pin6), EN3 (pin2), and EN4 (pin16) of the PMIC chip U1 are not input to the high level state, the second output channel VCH2 (pin22), the third output channel VCH3 (pin24), and the fourth output channel VCH4 (pin17) of the PMIC chip U1 are in a non-output voltage state. Therefore, by setting the required sequence of the input enable terminals of the three power supplies EN2, EN3, and EN4 of the PMIC chip U1, the power supplies of the second output channel VCH2 (pin22), the third output channel VCH3 (pin24), and the fourth output channel VCH4 (pin17) of the PMIC chip U1 can output voltage in the set sequence. The power output indications PG2 (pin23), PG3 (pin19), and PG4 (pin20) of the second, third, and fourth output channels of the PMIC chip U1 are in a high level state. The high level state of PG2, PG3, and PG4 indicates that the channel power voltage output state of the second output channel VCH2, the third output channel VCH3, and the fourth output channel VCH4 is normal.

[0084] PMIC chip U1 can combine 9 different VCH2, VCH3, VCH4 power output power-on timings according to the power input enable terminals EN2, EN3, EN4 and the power output indications PG2, PG3, PG4, that is, 3 to the power of 2 is 9. It is only necessary to weld or not weld resistors R1-R9 on the PMIC power module circuit board. The resistance values ​​are all 0 ohm resistors, which are used as wires. The following is the VCH2, VCH3, VCH4 power supply according to the circuit welding different resistors, and the PMIC chip U1 outputs different power-on timings:

[0085] ①. When R1, R2, and R3 are welded and the others are not welded (other resistor connection positions are disconnected), the output timing is: VCH1-VCH2, VCH3, VCH4.

[0086] ②. When R1, R2, and R5 are welded and the others are not welded (other resistor connection positions are disconnected), the output timing is: VCH1——VCH2, VCH3——VCH4.

[0087] ③. When R1, R4, and R3 are welded and the others are not welded (other resistor connection positions are disconnected), the output timing is: VCH1——VCH2, VCH4——VCH3.

[0088] ④. When R6, R2, and R3 are welded and the others are not welded (other resistor connection positions are disconnected), the output timing is: VCH1——VCH3, VCH4——VCH2.

[0089] ⑤. When R6, R2, and R5 are welded and the others are not welded (other resistor connection positions are disconnected), the output timing is: VCH1——VCH3——VCH2——VCH4.

[0090] ⑥. When R6, R9, and R3 are welded and the others are not welded (other resistor connection positions are disconnected), the output timing is: VCH1——VCH4——VCH3——VCH2.

[0091] ⑦. When R8, R2, and R7 are welded and the others are not welded (other resistor connection positions are disconnected), the output timing is: VCH1——VCH3——VCH4——VCH2.

[0092] ⑧. When R8, R4, and R3 are welded and the others are not welded (other resistor connection positions are disconnected), the output timing is: VCH1——VCH4——VCH2——VCH3.

[0093] ⑨. When R8, R9, and R3 are welded and the others are not welded (other resistor connection positions are disconnected), the output timing is: VCH1——VCH4——VCH2, VCH3.

[0094] Finally, the power supply and power-on timing requirements of different image sensors are set to realize a shared PMIC power module circuit board.

[0095] The PMIC chip U1 model of the PMIC power module circuit board is not limited and is applicable to power PMIC chips U1 with the same principle.

[0096] Second, as Figure 5 , Figure 5 1 is a flowchart of a specific implementation of a method for powering a camera module with high compatibility in the present application; a method for powering a camera module PMIC with high compatibility, adopting the camera power supply circuit of the first aspect, comprising:

[0097] S100: The processing chip processes the input first power supply voltage and outputs it through the first output channel to obtain a second power supply voltage;

[0098] S200, adjusting the second power supply voltage according to the camera type to obtain a third power supply voltage, and using the third power supply voltage to power each output channel;

[0099] S300, the processing chip outputs an enable control signal, and the timing of each enable control signal is adjusted by the timing control module 200 according to the camera type to obtain an enable output timing;

[0100] S400, adjusting the output voltages of the second output channel, the third output channel, and the fourth output channel according to the camera type, and outputting them to the camera module according to the enable output timing.

[0101] Preferably, Figure 6 , Figure 6 yes Figure 5 A flow chart of a specific implementation of S300, S300 includes: S310, electrically connecting the first input row of the timing adjustment unit to the output column; S320, electrically connecting any remaining input row to any two of the three output columns; S330, disconnecting / connecting the output column to the remaining input rows according to the camera type to adjust the timing of the enable control signal to obtain the enable output timing.

[0102] A highly compatible camera module PMIC and a power supply method thereof are implemented in the present invention. By setting a voltage regulation module 100, the voltage of each output channel can be adjusted according to the camera model. By setting a timing control module 200, the timing of the output channel can be adjusted according to the camera model, thereby meeting the power supply voltage and timing performance requirements of various models of cameras, improving the compatibility of the power supply circuit, shortening the R&D cycle, and reducing the R&D cost.
