The advantages and benefits of the present application can be realized and attained by practical performance or use of various embodiments of the method and apparatus disclosed herein with or without reference to the following examples. It is to be understood that the foregoing description is by way of example only and is not intended to limit the scope of the application as defined by the appended claims.
[0031] It is to be understood that the above-mentioned arrangements are merely illustrative for the principles of the present application and that numerous modifications and adaptions thereof are possible without departing from the spirit and scope of the present application.
[0032] In the following description, numerous specific details are discussed in order to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to one skilled in the art that the embodiments of the present application can be practiced without these specific details. In other instances, well-known structures and devices are not described in detail in order to avoid obscuring the embodiments of the present application.
[0033] The inventor has found that in an integrated circuit, only stable power supply can make the circuit work normally, and generally, the power supply chip is tested before use to judge the stability of the power supply capacity of the power supply chip, and when the stability of the power supply chip is within a certain range, the normal operation of the circuit can be ensured. In the related art, automatic testing of multiple power supply chips requires the combination of a test method and a large amount of hardware, and the test cost is increased, so that simultaneous measurement of multiple power supply chips is realized. Therefore, enterprises generally use manual testing, but the manual testing method has subjective judgment factors, which affects the test results. Because of the hot chip market, the testing demand increases, and manual testing faces problems such as long working hours, labor difficulty and labor shortage.
[0034] To solve the above problems, the present application provides a method and device for detecting multiple power supply chips, electronic equipment and medium. The working voltage of the power supply chip under rated load is collected, the working voltage is amplified, and the voltage error precision is calculated according to the amplified working voltage. The product quality of a single power supply chip is judged by comparing the voltage error precision with the preset voltage error precision range. The working voltage is converted to obtain the working current. The comprehensive evaluation result of the multiple power supply chips is obtained according to the load resistance value of the power supply chip, the voltage error precision corresponding to the product quality and the working current.
[0035] As Figure 1As shown, in an example embodiment of the present application, the method for detecting multiple power supply chips at least includes the steps of:
[0036] S110, obtaining multiple working voltages, the working voltage being a voltage generated by the power supply chip when connected to a rated load;
[0037] S120, amplifying the working voltage and calculating the voltage error accuracy based on the amplified working voltage, and determining the product quality of the power supply chip according to the voltage error accuracy and the preset voltage error accuracy range;
[0038] S130, voltage-current conversion is performed on the working voltage to obtain multiple working currents;
[0039] S140, obtaining the comprehensive evaluation result of the multiple power supply chips through the load resistance of the power supply chip, the voltage error accuracy corresponding to the product quality, and the working current.
[0040] In detail, in step S110, multiple working voltages are obtained, and the working voltage is a voltage generated by the power supply chip when connected to a rated load; for example, Figure 2 As shown, the method supplies power to multiple power supply chips through a power supply, the multiple power supply chips are connected to a rated load, the multiple power supply chips generate working voltages, and the multiple power supply chips are connected to corresponding detection circuits, for example, Figure 3 As shown, the detection circuit is a subtraction amplifier circuit, the working voltage output by a single power supply chip is collected through the resistor R5 in the detection amplifier circuit, the working voltage is the voltage across the resistor R5, that is, ΔV = V1-V2; after obtaining the working voltage, the comprehensive evaluation result of the multiple power supply chips is obtained through the calculation of the related parameters of the working voltage.
[0041] Because the working voltage value of the power supply chip collected is relatively small, in order to ensure that the calculated parameters are more accurate, for example, Figure 3 As shown, the working voltage is amplified through the subtraction amplifier circuit to obtain multiple amplified working voltages V0, and the amplified value of the amplified working voltage V0 is shown in expression (1):
[0042]
[0043] Wherein, V0 is the amplified working voltage, V1 is the voltage at the positive input end of the subtraction amplifier circuit, V2 is the voltage at the negative input end of the subtraction amplifier circuit, and resistor R1, resistor R2, resistor R3, and resistor R4 are resistors in the subtraction amplifier circuit.
[0044] In detail, in an example embodiment of the present application, the voltage error precision is calculated according to the amplified working voltage, including: acquiring the rated voltage corresponding to the plurality of amplified working voltages; performing subtraction proportional operation on the plurality of amplified working voltages and the corresponding rated voltages to obtain a plurality of voltage error precisions. It should be noted that the rated voltage corresponding to the plurality of amplified working voltages is also amplified by the corresponding multiple because the measured working voltage is amplified. The voltage error precision is obtained by performing subtraction proportional operation on the amplified working voltage V0 and the corresponding rated working voltage Vi, and the calculation expression of the voltage error precision is shown as (2):
[0045]
[0046] Wherein, V0 is the amplified working voltage, and Vi is the rated voltage corresponding to the amplified working voltage.
[0047] In step S120, the product quality of the power chip is judged according to the voltage error precision and the preset voltage error precision range, including:
[0048] In detail, in an example embodiment of the present application, the product quality of the power chip is judged according to the voltage error precision and the preset voltage error precision range, including: when the voltage error precision is within the preset voltage error precision range, the product quality of the single power chip is a genuine product; when the voltage error precision is outside the preset voltage error precision range, the product quality of the single power chip is a waste product. Wherein, the preset voltage error precision range is set to
[0049] ± 2%, when the voltage error precision is + 1.8% or the voltage error precision is - 1.9%, the voltage error precision is within the preset voltage error precision range, and the product quality of the single power chip is a genuine product; when the voltage error precision is + 2.5%
[0050] Or -2.3%, the voltage error precision is outside the preset voltage error precision range, and the product quality of the single power chip is a waste product.
[0051] In step S130, the working voltage is converted into voltage-current to obtain a plurality of working currents; the working voltage is converted into voltage-current, as shown in Figure 3 The current value flowing through the resistor R5 is collected, which is the working current, and after obtaining a plurality of working currents, the working current should also be processed.
[0052] In detail, in the example embodiment of the present application, after obtaining the working currents, the method further comprises: grouping the working currents into an array; and sorting the working currents according to a preset sorting condition, so that the sorted working currents are used for comprehensive evaluation of the power supply chips. The working currents of the plurality of power supply chips are grouped into an array, for example, the working currents of 5 power supply chips are 1A, 0.5A, 2A, 3.5A and 2.3A, and the working currents of the 5 power supply chips are grouped into an array A [1A, 0.5A, 2A, 3.5A, 2.3A]. The adjacent two working currents in the array A are compared, the preset sorting condition includes ascending order and descending order, if the preset sorting condition is ascending order, the first working current 1A in the array A is compared with the second working current 0.5A, the first working current 1A is greater than the second working current 0.5A, the first working current 1A and the second working current 0.5A are exchanged, if the previous working current is equal to or less than the next working current, the position is unchanged, the first working current is compared with other currents in turn, the adjacent two working currents are compared, until the previous working current is less than or equal to the next working current, and finally an array in ascending order is obtained
[0053] B [0.5A, 1A, 2A, 2.3A, 3.5A]; if the preset sorting condition is descending order, the first working current 1A in the array A is compared with the second working current 0.5A, the first working current 1A is greater than the second working current 0.5A, the first working current 1A and the second working current 0.5A are not exchanged, the second working current 0.5A is compared with the third working current 2A, the third working current 2A is greater than the second working current 0.5A, the third working current 2A and the second working current 0.5A are exchanged, until the previous working current is greater than or equal to the next working current, and finally an array C [3.5A, 2.3A, 2A, 1A, 0.5A] in ascending order is obtained.
[0054] In step S140, the comprehensive evaluation results of the plurality of power supply chips are obtained by the load resistance of the power supply chip, the voltage error accuracy corresponding to the product quality and the working current. The comprehensive evaluation results of the power supply chip are obtained by a plurality of parameters related to the power supply chip.
[0055] In detail, in the example embodiment of the present application, the step of obtaining the comprehensive evaluation result of the plurality of power supply chips comprises: performing weighted operation on the load resistance value of the power supply chip, the voltage error precision corresponding to the product quality and the working current according to the preset weight proportion, to obtain the comprehensive evaluation result of the plurality of power supply chips. The load resistance value of the power supply chip is a value specified in the power supply chip manual. For example, the weight proportion of each parameter is 20% for the load resistance value, 50% for the voltage error precision corresponding to the product quality and 30% for the working current, and the comprehensive evaluation result of the plurality of power supply chips is obtained by weighted calculation.
[0056] In detail, in the example embodiment of the present application, the method further comprises: storing the working current, the voltage error precision, the product quality and the working voltage, so as to facilitate subsequent data searching.
