Hi, guy,

Would please provide more information about your problem? such as attaching the wiring picture of the LP5024 EVM or some waveforms. and what did unable to detect the I2C address mean?

Before that, i hope you can measure whether the supply of VCC check point is corrcet? And when you send the address of device, can you receive the ackonwledge from the SDA?

Best Regards

Monet Xu
