    SLVUBQ3 – August 2019 TPS23882EVM: PoE, PSE, TPS23882 Evaluation Module This user’s guide describes the evaluation modules (EVM) for the TPS23882 (TPS23882EVM-008 and BOOST-PSEMTHR8-097). The EVM contains evaluation and reference circuitry for the TPS23882. The TPS23882 is a Power-over-Ethernet (PoE) device for power sourcing equipment (PSE).

  • Page 2: Description

    All other trademarks are the property of their respective owners. Description The TPS23882 features the TPS23882: an 8-channel, IEEE802.3bt compliant PoE PSE controller. The EVM consists of a motherboard (BOOST-PSEMTHR8-097) and a daughterboard (TPS23882EVM-008) containing one TPS23882 device. The TPS23882 EVM provides a multi-port base platform interface for TPS23882EVM-008, MSP-EXP430FR5969 (LaunchPad™), and...

  • Page 3: Tps23882 Voltage Rail Current Requirements

    LM5019 provides a basic power-on sequence and provides a well-controlled and consistent startup. In addition to 54 V, the TPS23882 requires 3.3 V for the digital circuitry and this is routed up to TPS23882EVM-008 over the connector interface. The current consumption is 6-mA typical and 12-mA maximum.

  • Page 4: Basic Setup Using Autonomous Mode

    2-pair ports are interoperable with PDs. Only 2P- 15W and 2P-30W are valid selections on the TPS23882EVM-008 as the other resistors are not populated. In order to test with autonomous mode, install a jumper on the pins of J5 corresponding to the desired...

  • Page 5: Basic Setup Using Usb2Any

    An I C interface is provided through J2 of the mother board to the TPS23882 device on the TPS23882EVM-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.

  • Page 6: Advanced Setup Using Launchpad

    Do not press the RESET button (S1) on the motherboard while communicating over I2C. Pressing this button will set all ports to off mode and the reference code will not be able to recover. TPS23882EVM: PoE, PSE, TPS23882 Evaluation Module SLVUBQ3 – August 2019 Submit Documentation Feedback...
