maximum power mode programming

Other Parts Discussed in Thread: TPS2388, TPS23861

Hello team,

 

My customer looks for PoE PSE controller which is pin programmable maximum power mode lilke LTC4279.

There are both ‘af’ port and ‘at’ port on customer board and they don’t want to deliver more power even if end user connects ‘at’ device to ‘af’ port,  due to thermal design.

Looking at TPS2388, it can detect PD classification automatically, but it seems we have to program maximum power with I2C communication.

Maximum power mode can be programmed without I2C/SPI programming in LTC4279. Do we have such device?

 

Best regards,

Taketo Sato
