- Page 3 Description www.ti.com Description The TPS23861EVM-612 features the quad port, TPS23861, IEEE 802.3at PoE PSE controller. The EVM consists of a motherboard (TPS23861EVM-612) and daughter board (TPS23861EVM-613) containing two TPS23861 devices. The TPS23861EVM-612 provides a multi-port base platform interface for TPS23861EVM-613, MSP-EXP430G2 (LaunchPad™), and USB-TO-GPIO (USB Interface Adapter).
- Page 4 The TPS23861 devices are pre-configured to operate in auto mode and, as such, no external communication interface is required to enable or configure the TPS23861EVM-612. A standard PD can be plugged into ports 1–4 and be expected to operate automatically.
