Hi Tom,
Thanks for your updates.
From LT4275 datasheet, it may need a >12.5V voltage between VPORT and GND, otherwise LT4275 may not turn on its classification regulator and result in low classification current. TPS23882B should make a 15.5V to 20.5V…
Part Number: TPS23882B Tool/software: We have recently moved from a 4 port ADI PSE to the 8 port TPS23882B PSE on our product line. Our new prototypes, which use 6 of the 8ports of the TPS23882B work fine as long as we use Cat5e/Cat6 cables to connect…
Part Number: TPS23882B Hi, Im using TPS23882B1 with two evaluation boards:
TPS23882B1EVM-008
BOOST-PSEMTHR8-097
Autonomous mode is selected via Jumper J5(2P-15W).
But PSE driver TPS23882B1 can detect other PD devices only if I do some manual settings in…
Hi Tommy,
Apologies for the delay in response, please see below my comments:
1. I highly recommend to use a buck converter instead of a resistor divider to achieve the 3.3V or VDD pin. VDD only has a absolute maximum rating of 4V and only using a resistor…
Part Number: TPS23882B Other Parts Discussed in Thread: TPS23881 , TPS23882 Hello expert,
Do we have a calculator or simulation tool to calculate TPS23881/TPS23882 thermal power dissipation based on port number / type(AT/BT). Customer would like to do the…
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 spec…
Part Number: TPS23882B Other Parts Discussed in Thread: TPS23882 Hi Sir,
Does the auto pin of TPS23882B only support af,at? If two pairs of functions, is bt type 3 class 6 supported?
Is there a test report for sifos or EA's bt type 3?
Part Number: TPS23882B My JDM informed me that TI FAE review the design and agree to allow MCU MSP430F using the same GND with TPS23882RTQR PoE PSE controller on 54V primary side, and this voltage is main source for PoE PSE power to PoE PD.
I'd like to…
