Part Number: LP3907
When I was configuring the output of LP3907SQ-JXQX/NOPB using I2C, I found that the values of all the registers of this chip were all 0xff. However, when I used a logic analyzer to capture the data, I found an ACK signal. Additionally, testing the other two devices on this I2C bus showed that they could read and write normally. Could it be that I have overlooked some necessary read/write operations for this chip?The figure below shows the data captured by the logic analyzer.
