MP8003A

IEEE 802.3af/at High Power PoE PD Interface with AUX Control

Datasheet

Description

The MP8003A is an IEEE, 802.3af/at, Power over Ethernet (PoE) compliant, powered device (PD), interface controller. The MP8003A has all the functions of IEEE 802.3af/at, including detection, 1-event and 2-event classification, input current control, and a 100V hot-swap MOSFET. The MP8003A sets the inrush current limit at about 120mA during start-up and switches to 840mA when the output pass MOSFET is turned on completely. A PG signal set to high indicates when the output is fully charged and pulls low when the output drops under the overload condition. The MP8003A also provides a T2P signal when it is connected to Type-2 power sourcing equipment (PSE). An auxiliary power input detector (AUX) provides a smooth power switch from PSE to an auxiliary wall adapter. The MP8003A also features built-in thermal protection and a wide-input UVLO hysteresis. The MP8003A is available in a QFN-10 (3mmx3mm) package.
