The EVLPOE007V1 is an evaluation tool dedicated to the use of the PM8805 device.

The evaluation board is designed to allow the testing of the PM8805 features and to verify the behavior of the component. See PM8805 datasheet for device description (see www.st.com).

The board can be used as a functional block in a complete PD design, having all possible features available to implement a demanding application circuit.

This data brief enounces the principal features only, all the characteristics and functionality of the evaluation board, are detailed in the application note (see www.st.com).

Key features
  • 74x66 mm (3x2.6 inch) P.C.B. dimension optimized to allow probe connection, component replacing, additional wiring.
  • Data & power input plus Data output RJ45 Ethernet connectors joined to a PoE signal path transformer, to meet Gbit and IEEE Std. 802.3 requirements.
  • Chassis ground plane connection, with 1.6 mm (65 mils) creepage distance to the Ethernet wire connections.
  • Adequate components available for EMC compliance and circuit setting in critical working conditions.
  • Classification resistors and dip switch available, for PD’s Class and Type selection.
  • Eight LEDs and two push-button placements, for PD’s status display and setting.
  • Single connector presence, for Rear or Frontal auxiliary source implementation.
  • Return path of the output voltage sectioned by a MOSFET, with control provided by the PG signal.
  • Twenty two test points or turrets, for signals monitoring and board output connection.
