MP8020GQV-Z

MP8020GQV-Z is an IEEE 802.3af/at/bt compliant, 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 control, and an internal 100V hot-swap MOSFET. It 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 MOSFET for high-power design. A high power good signal enables the use of a downstream DC/DC converter. It also provides automatic maintain power signature functionality under light loads. An auxiliary power input detector (AUX) and GATE2 driver provide a smooth power switch from the power-sourcing equipment to an auxiliary wall adapter with low power loss. Application includes security camera, video and VoIP phones, WLAN access point, internet of things devices, pico base stations.
