To measure a power IC chip, you can follow these steps:
< br >
1. Tools and devices: Prepare a digital multimeter (DMM) or oscilloscope, cable pliers, and other tools.
< br >
2. Determine the chip pin function: Find and download the chip specification or data book to understand the functional definition and electrical characteristics of the chip pin. This will help you determine which pins need to be measured and understand the electrical parameters you want to obtain.

4. Connect the measuring instrument: Use wire and wiring pliers to connect the measuring instrument to the corresponding chip pin. Ensure proper pin connections to avoid short circuits or incorrect connections.
< br >
5. Set the measuring instrument: according to the selected measurement mode, carry out the necessary Settings on the measuring instrument. For example, select the correct measurement range, adjust the sampling rate or time base, etc.
< br >
6. Measurement: Perform the corresponding measurement operation through the measuring instrument. For example, the DC voltage measurement mode is used to measure the output voltage of the IC chip, or the DC current measurement mode is used to measure the input current of the chip.

7. Analyze and record data: Perform data analysis according to the measurement results and record the data. This will help you evaluate the performance and working status of the chip.
The power chip and the power module are complex circuits composed of several components, which can not be measured by simple measuring tools such as multimeters. It is necessary to build a peripheral circuit that it can work normally, and use professional measuring instruments and equipment to measure.
