LP5861: I2C broadcast mode

Ulderico Arcidiaco
Prodigy 20 points
Part Number: LP5861

In the I2C Data Format section, the data sheet says "The device supports both independent mode and broadcast mode.". The address table below shows the broadcast address having the five most significant bits set to 10101. There is no further reference on how this mode works.

If I have another I2C device having the MSB 5 bits as 10101, will that conflict with the LP5861?

    Hi Ulderico,

    You can treat LP5861 have 2 I2C chip address, one is set by ADDRx pins and another is the broadcast address. If there is another device in the same I2C bus using the same chip address, the I2C commands will also control LP5861.
