Other Parts Discussed in Thread: TPS23861, TCA9517
I have a number of PCB's located in a 19" rack enclosure. Each PCB contains multiple TPS23861 PoE PSE devices which can be linked together using i2c and interrogated.
The i2c bus can run upto 400kHz and is at 3v3.
Ideally i want to run the i2c through all the boards and have one connection point for the interogation device. Each PCB would have and i2c input and output connector which would link together in-out>in-out>in-out
I've looked at the TI "I2C Level Shifters, Buffers, and Hubs" but nothing strikes me as suitable and i don't need to level shift.
Any suggestions as to which part(s) i should look at to achieve the above, or am i making things more complicated than i need to.
thanks,
