Datasheet Summary
DESCRIPTION
The MP8020 is an IEEE 802.3af/at/btpliant, Power over Ethernet (PoE), powered device (PD). The device supports all the functions of IEEE 802.3af/at/bt, including detection, 5-event classification, input current (IIN) control, and an internal 100V hot-swap MOSFET.
The MP8020 provides configurable inrush current limiting during start-up and operation current limiting when the internal MOSFET is fully turned on. The GATE1 driver supports the use of an external low on resistance (RDS(ON)) MOSFET for high-power design. A high power good (PG) signal enables the use of a downstream DC/DC converter. The MP8020 also provides automatic maintain power signature functionality under...
