Tool/software:

Dear Sir,

I am planning to use the LP5810 and LP5024 ICs in my design, both of which use the I²C protocol for communication. I have the following query:

Can both the LP5810 and LP5024 be controlled using a single I²C bus, or will there be any address conflicts? If there is a conflict, what would be the recommended approach to resolve it?

I would appreciate your guidance on this.

Best regards,
Ravi G

Hi Ravi,

Yes, a single I2C bus can be used to control both the LP5810 and LP5024. As you can see the first 3 bits of the slave address of the LP5024 and LP5810 are different, so you can control them independently.

Best regards,

Felix
