Abstract: A test system study is carried out based on the electrical characteristics of a typical power supply monitoring circuit TPS3307-18M, and the electrical parameter characteristics of this product are analyzed. The overall function implementation of the test system, the use of peripheral instruments and equipment, the test accuracy, the reliability assessment and other aspects are evaluated, and the hardware design of the test system is completed through the design of the power supply module, the control module and the self-contained constant-current source module, etc. The Visual Basic programming is used to achieve the upper computer interface and control operation. Finally, the development of the test system of the power supply monitoring circuit is realized, providing ideas and references for the development and design of test system for similar products.
