描述 Description

The MK3614 is a high-density integrated autonomous single Ethernet port power sourcing equipment (PSE) controller designed for use in IEEE 802.3af/at Power over Ethernet (PoE) systems. The device provides powered device (PD) detection, classification, current limit, load disconnect detection, and operating current levels. The device features intelligent protection circuitry and allows the delivered to PD power up to 30W. The device integrates a 0.3Ω power MOSFET and a current-sensing resistor, which enables the non-PoE protocol adapter to be feasibly retrofitted into a PSE adapter with the PoE protocol only requiring a few external components.
