PD64001 1-Port PoE Manager Datasheet
Preliminary
Introduction ________________
The PD64001 is a single-port Power over Ethernet
PSE (Power Source Equipment) Manager. The PSE
Manager allows for the detection of IEEE 802.3af-
2003 and IEEE802.3at/D3.0 powered devices,
ensuring safe power feeding and monitoring of
Ethernet ports. With a minimum of external
components, the PD64001 integrates in a one-port or
two- port PoE-port switches and Midspans.
The PD64001 has several operating modes, allowing
it to be tailored to the customer application, be it a
Switch or a Midspan, IEEE802.af or
IEEE802.3at/D3.0-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 supports 2-events classification and
operates at Iport_max currents of up to 720mA per
port, making it fully compliant with the
IEEE802.3at/D3.0
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.
This document allows the designer to integrate PoE
capabilities, as specified in the IEEE802.3af standard
into an Ethernet switch, Midspan or a Router.
