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
TPS23882B1EVM-008,

MSP-EXP430FR5969

(LaunchPad

™

), and

(USB Interface Adapter).

1.1 Features

The EVM supports the following features:

• Eight IEEE802.3bt 2-pair ports with 1000BASE-T (gigabit Ethernet data pass-through)
• Single DC power supply input
• Onboard 3.3-V regulator
• Onboard I

2

C interface to the TPS23882B1 device from either

MSP-EXP430FR5969

.

• Port ON status LEDs
• Reset button for easy reconfiguration
• User test points

1.2 Applications

The EVM is used in the following applications:

• Enterprise and SoHO switches and routers
• Connected ceiling LED switches
• PoE pass-through power modules
• Network video recorders (NVRs)
• Wireless backhaul and small-cell networking
