| titleOfInvention | Current test circuit of camera module |
| abstract | The utility model provides a current test circuit of a camera module, which comprises a main control chip, a connector CN1 for connecting the camera module to be tested and a functional chip for current test, wherein a power supply pin of the connector CN1 is connected with a test resistor in series, two ends of the test resistor are connected to a monitoring pin of the functional chip, a capacitor is connected to the test resistor in parallel, and the functional chip is electrically connected with the main control chip through a communication port. In the utility model, the main control chip and the functional chip for current testing are communicated through I2C, and compared with the oscilloscope test, the current testing circuit provided by the utility model has the advantages of low cost, high speed and simple operation. The current test circuit provided by the utility model can quickly test the current data of the pin of the camera module, and records the data at the computer end through the serial port communication between the main control chip and the computer, so that the current test circuit is simple and convenient to operate, low in price and capable of being used for large-scale batch test. |
