Hi Ufuk,
TPS23861 and TPS23882 have similar fault detection mechanism. Please check this FAQ out.
TPS23861 and TPS23882 have same ILIM (mainly for short circuit during normal operating after inrush) and Inrush (only during inrush stage) protection…
Part Number: TPS23882B Other Parts Discussed in Thread: LM5017 , TPS23882EVM-084 , TPS23881 , TPS23882 Dear Team,
Due to our protential customer are interesting the Marvell – IRONMAN projects, and would like to add the PoE functional into product…
Hi Franz,
For the PSE side, I recommend either TPS23861 or TPS23882(B). See below for more details:
TPS23861: 4-channels, Type-2 2-pair 802.3at, autonomous mode, 0.255Ohm Rsense. For smaller design TIDA-00465 should work.
TPS23882(B): 8-channels…

Several chips of TPS2881 is used for POE at interfaces in the AC5X switchboard.When it has a sifos at test,the parameter of Tlim_1 in theTest: pwron_maxi doesn…
Hi Ufuk,
We don't provide FirmPSE source code as this is a production ready software solution that host can configure the system through I2C or UART. However, you can refer to TPS23861 MSP430 reference code for power management algorithm and TPS23882…
Hi,
What a pity! What a strange choice that prevent an I2C master controlled by DMA to read the current and voltage of all the channels in a raw. As any I2C devices, MAX5980 enables this and it is so efficient!
Maybe one day, a tps23882 will correct…
Hi Edward,
These ICUT thresholds are fixed so 110mA is the lowest you can set the TPS23861.
You may want to look at the TPS23882. This is able to go down to 4W and increase in increments of 0.5W. This looks at the total power rather than a current…
Hi Louis,
Please request access through TPS23882 product folder (ti.com has gone through some changes recently and the note it missing from TPS23881 product folder. we will add links back to TPS23881 folder)and we will grant your access today. Thanks…
