Feature Description
PD64001/H features
The PD64001/H meets all IEEE-802.3af-2003 standard requirements including:
Multi point resistor detection
IEEE 802.3af-2003
PD classification function
Compliant
AC disconnect and DC disconnect function
Supports Back-off feature for Midspan implementation
IEEE802.3at-draft4.2
Including support for high power and 2-events classification.
Compliant
The PD64001/H requires a single DC voltage source: 44V to 57V. No additional
Single DC voltage Input
voltage sources (e.g. 3.3V/5V) are required for the PoE systems operation.
The PD64001/H can operate over a wide temperature range: -40 C to +85 C.
Wide temperature range:
This temperature range enables the integration of the PD64001/H into small
-40c to +85c
unventilated boxes and operates in harsh environments.
The PD64001/H has a very low thermal dissipation. The Rsense in the PD64001/H
Low thermal dissipation
applications is only 1 to keep the peripheral components in low temperatures as
(1 sense resistor)
well.
External Mosfet is utilized to increase the flexibility of the solution, enabling it to be
External Power FET
tailored to the customer power requirements.
The PD64001/H utilizes a dedicated pin, allowing an immediate disconnection of the
H/W Disable Port
PoE port. This disable-port pin input can be controlled via the Host CPU.
Pre-Standard PD
Enables the detection and powering of pre-standard power devices (PDs).
Detection
Detection of Cisco Enables the detection and powering of all Cisco devices including pre-standard
