[0002] At present, the company's BQ series power management IC burner calibration and verification integrated equipment has a relatively high manufacturing cost, and the number of multimeters used for each equipment is two. The proportion of equipment expenditure is relatively high, which increases the cost of the enterprise and reduces the benefit
At the same time, the existing BQ series power management IC programming, calibration and verification integrated equipment uses the module circuit of "split control multimeter" to separately control the voltage and current reference test, so that the two multimeters correspond to each other to test the voltage and current reference, while There is still a lot of room for improvement in this voltage and current reference sampling method to reduce equipment manufacturing costs

Embodiment Construction
[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0035] Please refer to figure 1 , a power management IC burning calibration verification method, the method comprising:
[0036] S100: Integrate the circuit for controlling voltage reference sampling and the circuit for controlling current reference sampling in a new module;
[0037] S200: The voltage reference sampling circuit controls the multimeter in parallel with the multimeter. The voltage reference sampling point is the B+ and B- test points of the product; the current reference sampling circuit controls the multimeter in series with the multimeter. The current reference sampling point is t...

The invention discloses a method for burn calibration and verification of an electric power management IC. The method comprises the following steps that a circuit for controlling voltage reference sampling and a circuit for controlling current reference sampling in a circuit are integrated into a new module; the voltage reference sampling circuit controls a universal meter to be connected to the universal meter in parallel, and voltage reference sampling points are B+ and B- test points of a product; the current reference sampling circuit controls the universal meter to be connected to the universal meter in series, and current reference sampling points are B+ and P- test points of the product; voltage reference collection and current reference collection use one test point B- simultaneously; and the two modular reference sampling circuits are called in a relay switching mode. Through adoption of a transformed 20-channel burn calibration and verification integrated device, only one Agilent universal meter is needed, so that the production cost is reduced and the investment is saved.
