    TPS23882B1EVM: PoE, PSE, TPS23882B1 Evaluation Module ABSTRACT This user’s guide describes the evaluation modules (EVM) for the TPS23882B1 (TPS23882B1EVM-008 and BOOST-PSEMTHR8-097). The EVM contains evaluation and reference circuitry for the TPS23882B1. The TPS23882B1 is a Power-over-Ethernet (PoE) device for power sourcing equipment (PSE).

  • Page 2: Description

    1 Description The TPS23882B1 features the TPS23882B1: an 8-channel, IEEE802.3bt compliant PoE PSE controller. The EVM consists of a motherboard (BOOST-PSEMTHR8-097) and a daughterboard (TPS23882B1EVM-008) containing one TPS23882B1 device. The TPS23882B1 EVM provides a multi-port base platform interface for ™...

  • Page 3: Quick Start

    In addition to 54 V, the TPS23882B1 requires 3.3 V for the digital circuitry and this is routed up to TPS23882B1EVM-008 over the connector interface. The current consumption is 6-mA typical and 12-mA maximum.

  • Page 4: Basic Test Setup Using Autonomous Mode

    2-pair ports are interoperable with PDs. Only 2P-15W and 2P-30W are valid selections on the TPS23882B1EVM-008 as the other resistors are not populated. To test with autonomous mode, install a jumper on the pins of J5 corresponding to the desired power level and...

  • Page 5: Basic Test Setup Using Usb2Any For I

    An I C interface is provided through J2 of the motherboard to the TPS23882B1 device on the TPS23882B1EVM-008. The USB2ANY adapter (not included) can be used with any TI GUI which uses USB2ANY to read and write over an I C bus.
