TPS92390: Question: I2C address conflict with Mutiple devices?

Alexander Beal

Part Number: TPS92390

Tool/software:

Hello,

I would like to use 8 TPS92390 to driver 8 separate LEDs and control them as I2C devices with a single STM32. Is it possible to set the I2C address of each device to be unique?

Thanks

Hi Alexander,

TPS92390 supports two I2C addresses as 0x3B and 0x3A only and it can not be used for 8 separate LED drivers' control.

Thanks for you quick reply. Are there any TI LED drivers that support multiple devices (~8) on the same I2C bus or is this a universal thing with I2C on TI LED drivers?

Hi Alex,

Currently our devices all support up to two I2C addresses.
