The PSE Manager allows for the detection of IEEE 802.3af- 2003 and IEEE802.3at-draft4.2 powered devices, ensuring safe power feeding and monitoring of Ethernet ports. With a minimum of external components, the PD64001/H integrates in a one-port or two-port PoE-port switches and Midspans. The PD64001/H has several operating modes, allowing it to be tailored to the customer's application, be it a switch or a Midspan, IEEE802.af or IEEE802.3at-draft4.2-compliant, with 1-event or 2-events classification, AC or DC disconnect and strict resistor detection or legacy detection capabilities. It operates in a total stand-alone mode, with no need for user intervention. The PD64001/H supports 2-events classification and operates at Iport_max currents of up to 600 mA / 720 mA (in coordination with PD64001 / PD64001H) per port, making it fully compliant with the IEEE802.3at-draft4.2 This datasheet includes a complete application note and provides detailed information and circuitry design guidelines for the implementation of a 1-port Power over Ethernet (PoE) system, based on Microsemi’s™ 1-channel PoE device, the PD64001/H. This document allows the designer to integrate PoE capabilities, as specified in the IEEE802.3af standard into an Ethernet switch, Midspan or a router.
