DESCRIPTION
EV8003A-Q-00A Evaluation Board is designed
to demonstrate the capability of MP8003A`s
function. MP8003A is an IEEE 802.3af/at
power-over-Ethernet (PoE) compliant powered
device (PD) interface controller. It has all the
functions of IEEE 802.3af/at.
MP8003A sets 120mA inrush current limit and
840mA operation current limit, a PG signal sets
to high to indicate output fully charged, and it
pulls low when Vout drops in overload condition.
MP8003A also provides a T2P signal when it is
connected to a type 2 power sourcing
equipment (PSE).
An AUX pin of MP8003A provides smoothly
power switch from PSE to auxiliary wall adaptor.
MP8003A also features built in thermal
protection and wide input VULO hysteresis.
The MP8003A is available in a 10-pin QFN
(3mm×3mm) package.
